Prim-O-Glucosylcimifugin 97.0%(HPLC)

Primuline has been used as a reagent in the preparation of lipids for chloroplast lipid membrane.It has been used as a dye in preparative thin-layer chromatography (TLC).

For R&D use onlynot for drug household or other uses.

Primuline is a dye containing the benzothiazole ring system. Primuline itself is also known as Direct yellow 7 Carnotine or C.I. 49010. The primulines are considered derivatives of dehydrothiotoluidine (aminobenzenyltoluylmercaptan) which is obtained when para-toluidine is heated with sulfur for eighteen hours at 180-190 &8451 and then for a further six hours at 200-220 &8451 Dehydrothiotoluidine is not itself a dye-stuff but if the heating is carried out at a higher temperature in the presence of more sulfur then a base is formed which gives primuline yellow upon sulfonation.
