2-acetonyl-7-hydroxy-5-methyl-chromen-4-one CAS 40738-40-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-acetonyl-7-hydroxy-5-methyl-chromen-4-one.

2-acetonyl-7-hydroxy-5-methyl-chromen-4-one (CAS 40738-40-7), molecular formula C13H20O4 and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-acetonyl-7-hydroxy-5-methyl-chromen-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.30 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.

As a certified reference material (CRM), 2-acetonyl-7-hydroxy-5-methyl-chromen-4-one 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.
