(S)-Equol 4’-Sulfate Sodium Salt CAS 688025-52-7 chemical structure

Description

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

(S)-Equol 4’-Sulfate Sodium Salt (CAS 688025-52-7), molecular formula C15H13O6SNa and molecular weight 344.31 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-Equol 4’-Sulfate Sodium Salt (C15H13O6SNa) contains a flavonoid core, a sulfone group, 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).

CATO manufactures (S)-Equol 4’-Sulfate Sodium Salt 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.
