Meta-Ester (间位酯) - Reactive Dye Intermediate, CAS 2494-88-4, HPLC ≥96%

产品描述

Meta-Ester (间位酯), chemical name m-(β-Sulfato ethyl sulfone) aniline (2-[(3-aminophenyl)sulfonyl]ethyl hydrogen sulfate), CAS NO. 2494-88-4, molecular formula C8H11NS3O5. Appearance: light white / greyish white powder. Chromatographic value (HPLC) ≥96% (≥90% min). Meta-Ester is an important intermediate for synthesizing vinyl sulfone type reactive dyes, and the main intermediate for KN-R, KN and M type reactive dyes. It does not contain other reactive groups in the molecule, so the β-hydroxyethyl sulfone sulfate ester generates insoluble small-molecule dyes during dyeing, which can then dye synthetic fibers in the form of disperse dyes. Quality control: intermediate control of chemical methods + tracking control of liquid chromatography (HPLC).
