4-Benzyl-gallic Acid Benzyl Ester CAS 1159977-07-7 chemical structure

Description

CATO manufactures 4-Benzyl-gallic Acid Benzyl Ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

4-Benzyl-gallic Acid Benzyl Ester (CAS 1159977-07-7), molecular formula C21H18O5 and molecular weight 350.36 g/mol, is a CATO reference standard with documented purity and traceability.

4-Benzyl-gallic Acid Benzyl Ester (C21H18O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
