1-(2-Pyridylazo)-2-resorcinol (PAR), an orange colored dye, is commonly used as an acid-base indicator. It can form chelates with metal ions, which makes it a valuable indicator in complexometric titrations. 1-(2-Pyridylazo)-2-resorcinol is an indicator in complexometry and a reagent for the extraction and spectrophotometric determination of many transition metals.
Applications:
4-(2-Pyridylazo)resorcinol monosodium salt is a useful indicator in complexometry, as well as a reagent for the extraction and spectrophotometric determination of many transition compounds. It is a highly selective and sensitive reagent for cobalt and iron. 4-(2-Pyridylazo)resorcinol monosodium salt is also a useful reagent for selective determination of trace level chrome(III) by ion-pair reversed-phase high-performance liquid chromatography.

Xylenol Orange tetrasodium salt is a salt form of Xylenol orange. Xylenol Orange is a fluorochrome useful in single and polychrome sequential labeling because it remains fixed to calcified tissues until removal of bone minerals. The fluorescence in xylenol orange is in contrast to the fluorescence of other known dyes thus allowing for easier identification of certain regions of a slide. In addition, the fluorescence labeling sites are the same for xylenol orange and other tetracylines such as fluoresceins and calcein blue. Further studies have shown that xylenol orange is used to detect lipid hydroperoxide in low density lipoproteins by oxidizing ferrous ions from Fe2+ to Fe3+ under acidic conditions. After oxidation of ferrous ions, a Fe3+ xylenol orange complex is formed which can be measured spectrophotometrically at 560 nm.
Applications:
Xylenol Orange tetrasodium salt is used as a photometric reagent and a metal indicator. An organic reagent, most commonly used as a tetrasodium salt as an indicator for metal titrations. It is a versatile indicator for EDTA titrations in acidic range. It is a common organic reagent used as an indicator for metal titrations.Fluorochrome useful in single and polychrome sequential labeling of calcifying tissues because it remains fixed to calcified tissues until removal of bone minerals. Can also be used to detect lipid hydroperoxide in low density lipoproteins by oxidizing ferrous ions from Fe2+ to Fe3+ under acidic conditions. After oxidation of ferrous ions, a Fe3+ Xylenol orange complex is formed which can be measured spectrophotometrically at 560 nm.
Chemical Name
N, N-diethyl 4-phenylenediamine sulfate (1:1)
InChI Key
AYLDJQABCMPYEN-UHFFFAOYSA-N
Solubility
Soluble in water; slightly soluble in ethanol, methanol.
A product for proteomics research, N, N-Diethyl-p-phenylenediamine sulfate is used for the spectrophotometric determination of drugs such as salbutamol sulphate, ritodrine hydrochloride and isoxsuprine hydrochloride containing phenolic group.Use of N, N-diethyl-p-phenylenediamine sulphate for the spectrophotometric determination of some phenolic and amine drugs.
Applications:
N, N-Diethyl-p-phenylenediamine has been employed as a reference probe to investigate rapid chlorination rate constants by a stopped-flow spectrophotometric competition kinetics method. The reaction of chlorine and N, N-diethyl-p-phenylenediamine for sensitive square-wave voltammetric detection of chlorine has been studied and used to investigate the role of H2S in cardioprotection induced by ischemic preconditioning in rat heart, in spectrophotometric determination of gold(III) in gold-pharmaceuticals such as sodium aurothimaleate and auranofin and to investigate colonic tissue H2S production using the acetate trapping assay system.
