Chemical Structure

Ethyl 4-6-O-benzylidene-β-D-thioglucopyranoside CAS 20701-61-5 chemical structure

Description

Ethyl 4-6-O-benzylidene-β-D-thioglucopyranoside (C15H20O5S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ethyl 4-6-O-benzylidene-β-D-thioglucopyranoside (CAS 20701-61-5) is a high-purity analytical reference standard with the molecular formula C15H20O5S and a molecular weight of 312.38 g/mol.

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

As a certified reference material (CRM), Ethyl 4-6-O-benzylidene-β-D-thioglucopyranoside meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
