Chemical Structure

Methyl 2-3-di-O-benzyl-4-6-O-benzylidene-α-D-mannopyranoside CAS 51842-18-3 chemical structure

Description

Methyl 2-3-di-O-benzyl-4-6-O-benzylidene-α-D-mannopyranoside (CAS 51842-18-3), molecular formula C28H30O6 and molecular weight 462.53 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 2-3-di-O-benzyl-4-6-O-benzylidene-α-D-mannopyranoside (C28H30O6) contains a steroid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Methyl 2-3-di-O-benzyl-4-6-O-benzylidene-α-D-mannopyranoside 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.
