3.4- Dichlorobenzene sulfonate, amino

Diclofenac and six metabolites (e.g., hydroxydiclofenac, dihydroxydiclofenac sul te, 4-amino-3,5-dichlorobenzene sulfonic acid) were isolated fi om urine and separated on a C, column ( = 282 nm). A 95/5 40/60 (at 20min) - 0/100 (at 22 min hold 4 min) water (10 mM ammonium formate at pH 7.0)/methanol gradient gave excellent separation. Time-of-flight MS was used to confirm peak identity [496]. 

In the synthesis of the disulfonated 1 2 chromium complex dye 16 [82269-28-1] [28], a mixture of the azo compound made from diazotized 2-amino-1,4-dichlorobenzene-5-sulfonic acid and salicylaldehyde is heated to 50 °C with...
