Maleic hydrazide is a synthetic compound which has a plant growth regulating action. It is used as a foliar treatment of potatoes to prevent volunteer formation and sprouting during storage. It can also be used pre-harvest to suppress sprout formation in onions. Maleic hydrazide has a mutagenic effect on the cells and prevents cell division in tubers as well as an inhibitory effect on biosynthetic activity. It is also used in combination with various herbicides (dicamba and MCPA) as well as fatty acids, to control unwanted vegetation in amenity turf and ornamental gardens.
Bronopol (INN) is an organic compound that is used as an antimicrobial. It is a white solid although commercial samples appear yellow. The first cited synthesis of 2-Bromo-2-nitro-1, 3-propanediol is 1897 according to Molbase.
Bronopol was invented by The Boots Company PLC in the early 1960s and first applications were as a preservative for pharmaceuticals. Owing to its low mammalian toxicity(at in-use levels) and high activity against bacteria (especially the troublesome Gram negative species), [1] bronopol became popular as a preservative in many consumer products such as shampoos and cosmetics. It was subsequently adopted as an antimicrobial in other industrial environments such as paper mills, oil exploration and production facilities, as well as cooling water disinfection plants
Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na2SO3. A pale yellow, water-soluble solid, it is used commercially as an antioxidant and preservative. A heptahydrate is also known but it is less useful because of its greater susceptibility toward oxidation by air.
Sodium sulfite (CAS 7757-83-7) is an odorless, solid white powder with a salty sulfurous taste that is soluble in water. It is primarily used as a food preservative (e.g., to prevent dried fruit from discoloring) and as an antioxidant. In the past, sodium sulfite was used to make pulp in the paper industry, but its use now accounts for less than 10% of the total pulp production, and the number of sulfite mills continues to decrease. Sodium sulfite is also used water treatment and photography. There is very little information on the environmental fate and effects of sodium sulfite and it is anticipated that, if released to water or soil, the effects would be negligible. Because it is used in small amounts as a food preservative, a very small percentage of the population is ‘sensitive’ to the chemical and may have an allergic reaction; some asthmatics may have a severe reaction following exposure. There are no environmental standards or regulations for sodium sulfite as it is ‘generally recognized as safe’ when used as a chemical preservative.
Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins.
Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes.
Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. Other reactions with phthalic anhydride yield phenolphthalein, benzoic acid, phthalylsulfathiazole (an intestinal antimicrobial agent), and orthophthalic acid.

UsesThe compound is a high-tonnage chemical and is widely used in a variety of industrial organic syntheses.
UsesPhthalic anhydride is used in the manufacture of unsaturated polyesters and as a curing agent for epoxy resins. When used as a pigment, it can be responsible for sensitization in ceramic workers.

Silica Gel Property
red phosphorus may be formed by heating white phosphorus to 300 c (572 f) in the absence of air or by exposing white phosphorus to sunlight. Red phosphorus exists as an amorphousnetwork. Upon further heating, the amorphous red phosphorus crystallizes. Red phosphorus does not ignite in air at temperatures below 240 c (464 f), whereas pieces of white phosphorus ignite at about 30 c (86 f). Ignition is spontaneous at room temperature with finely divided material. Heating red phosphorus in the presence of moisture creates phosphine gas, which is both highly flammable and toxic.
applications
red phosphorus can be used as a very effective flame retardant, especially in thermoplastics (e.g. Polyamide) and thermosets (e.g. Epoxy resins or polyurethanes). The flame retarding effect is based on the formation of polyphosphoric acid. Together with the organic polymer material, this acid creates a char which prevents the propagation of the flames. The safety risks associated with phosphine generation and friction sensitivity of red phosphorus can be effectively reduced by stabilization and micro-encapsulation. For easier handling, red phosphorus is often used in form of dispersions or masterbatches in various carrier systems.

More about Thiomalic Acid The first chemical contrast of thiols and sulfides with alcohols and ethers is acidity, which is important in organic reactions. Thiols are stronger acids than relevant alcohols and phenols. Thiolate conjugate bases are easily formed, and are excellent nucleophiles in SN2 reactions of alkyl halides and tosylates. The nucleophilicity of sulfur is much greater than that of oxygen, resulting in a number of useful electrophilic substitution reaction that are rare by oxygen. For example, sulfides form (with alkyl halides) ternary sulfonium salts, in the same alkylattion of tert-amines quaternary ammonium salts, whereas ternary oxonium salts are prepared only under extreme conditions. Without exception, sulfoxides, sulfinate salts and sulfite anion also alkylate on sulfur, despite of the partial negative formal charge on oxygen and partial positive charge on sulfur. The second character is the oxidation states of sulfur. Oxygen has only two oxidation states, whereas sulfur covers from –2 to +6 as follows :
One more sulfur compound's contrast with oxygen analog is in oxidation chemistry. Oxidation of sulfur compounds changes the oxidation state of sulfur rather than carbon, whereas, oxidation of alcohols to aldehydes and ketones changes the oxidation state of carbon not oxygen. Thiols is oxidized to S-S single bond (disufide) which is stronger than O–O bond in peroxide. Disufide forms sulfenyl chlorides (with chlorine in mild condition) or sulfonic acids under harder condition. Oxidation of sulfides with hydrogen peroxide (or peracids) yields sulfoxides and then to sulfones. A certain sulfoxide compound such as dimethyl sulfoxide can be used as an effective oxygen source in the oxidation reaction of primary and secondary alcohols to aldehydes and ketones. DMSO easily is reduced to dimethyl sulfide and water is taken up by the electrophile. oxidation procedure is very mild and tolerates a variety of other functional groups, including those having oxidizable nitrogen and sulfur atoms.
