Sulfonic Para Base Ester (磺化对位酯) - CAS 42986-22-1, HPLC >93%

Description

Sulfonic Para Base Ester (磺化对位酯), chemical name 4-(β-hydroxyethylsulfonyl) aniline-2-sulfonic acid, abbreviation 磺化对位酯, CAS NO. 42986-22-1, molecular formula C8H11NS3O5. Appearance: light pink powder. Amino value >90%, chromatographic value (HPLC) >93%. Mainly used to synthesize KN type, M type and other reactive dyes. Because a sulfonic acid group is introduced at the ortho position of the amino group in the para-ester molecule, the reactivity of the vinyl sulfone group is increased, so the reactivity of the reactive dyes synthesized from this product is correspondingly increased, and the dyeing rate is significantly improved. It is the main intermediate for synthesizing reactive red, yellow, blue, light and brilliant color dyes. Quality control: intermediate control of chemical methods + tracking control of liquid chromatography (HPLC).
