PINACYANOL CHLORIDE Chemical Properties,Usage,Production

Chemical Properties OLIVE-GREEN TO GREEN-BLACK POWDER
Uses Histological stain (chromosomes).
Biological Activity Pinacyanol chloride (1, 1-diethyl-2, 2-carbocyanine chloride), also known as quinaldine blue or PIN, belongs to the class of symmetric trimethinecyanine dyes. It is widely used as a histological stain. Pinacyanol chloride is used in the study of bacterial polysaccharides. Pinacyanol chloride exposure induces respiratory immunogenicity. PIN has two absorption maximums at 605nm and 550nm, which are known asα and β bands respectively.
Purification Methods Crystallise the dye from EtOH/diethyl ether. The iodide [605-91-4] crystallises from MeOH or EtOH with m 298-299o(dec) . [Beilstein 23 H 320, 23 I 89, II 282, III/IV 2064, 23/10 V 129.]
