Blumeatin B CAS 79995-67-8 chemical structure

Description

Blumeatin B (CAS 79995-67-8), molecular formula C17H16O7 and molecular weight 332.30 g/mol, is a CATO reference standard with documented purity and traceability.

Blumeatin B (C17H16O7) 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 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), Blumeatin B 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.
