20931-58-2 ISOCRYPTOMERIN CAS 20931-58-2 chemical structure

Description

As a certified reference material (CRM), 20931-58-2 ISOCRYPTOMERIN 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.

20931-58-2 ISOCRYPTOMERIN (CAS 20931-58-2), molecular formula C31H20O10 and molecular weight 552.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 20931-58-2 ISOCRYPTOMERIN is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 552.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
