a) Appearance | A pale cream coloured powder, odourless. |
b) Identification | i) Infra-red absorption spectrum concordant with reference spectrum for Oxyclozanide (Polymorph B). ii) The light absorption, in the range 250 to 350 nm of a 0.003% (w/v) solution in acidified methanol exhibits a maximum only at 300 nm. The absorbance at the maximum is about 0.76. |
