1796-92-5 Usage
Uses
Chromeazurol B (cas# 1796-92-5) is a pH-sensitive dye based on a hydroxytriarylmethane core and two carboxylate functional groups, allowing for facile coordination to metal centres, and for the preparation of coordination polymers. Chromeazurol B is used as a sensitive stain for aluminimum in undecalcified cancellous bone. Dyes and metabolites.
Preparation
2,6-Dichlorobenzaldehyde?and 2-Hydroxy-3-methylbenzoic acid condensation, the product oxidation and changed into sodium salt.
Properties and Applications
brilliant blue to red light navy blue. Brown powder. Soluble in water for brown light yellow, solubility for 100 g/l (80 ℃), slightly soluble in alcohol for yellow olive brown. Dye in concentrated sulfuric acid for red, with golden yellow after diluted. Its aqueous solution for yellow light brown, add sodium hydroxide solution into purple blue. Dyed the metal sensitivity smaller. Mainly used for dyeing wool, colour and lustre is brilliant light, good levelness. Fine, carded wool fabric are can be used. Also can be dyed silk and nylon. Can be in acetic acid chromium pretreatment of wool fabric direct printing, also can be used in the leather dyeing and used as organic pigment.

Check Digit Verification of cas no
The CAS Registry Mumber 1796-92-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,9 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1796-92:
(6*1)+(5*7)+(4*9)+(3*6)+(2*9)+(1*2)=115
115 % 10 = 5
So 1796-92-5 is a valid CAS Registry Number.
