Air & Water Reactions
Insoluble in water.
It crystallises from EtOH as the hydrochloride and is very slightly soluble in CHCl3, UV: 434nm ( 370). The free base (carbinolamine) has m 136o (from *C6H6). [Goldacre & Phillips J Chem Soc 1724 1949, Conrad et al. Biochemistry 9 1540 1970, Beilstein 14 IV 256.]
ChEBI: A hydrochloride obtained by combining 4,4'-carbonimidoylbis(N,N-dimethylaniline) with one molar equivalent of hydrogen chloride. A fluorescent stain for demonstrating acid fast organisms in a method similar to the Zieh
Neelsen. It also can be used to make a fluorescent Schiff reagent.
Yellow flakes or powder.
Certified for use by fluorescence microscopy in Churukian's modification of Truant's fluorescent method for acid fast bacilli on paraffin sections.
