6,7-Dihydroxy-3,4-dimethyl-2H-chromen-2-one CAS 16574-11-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dihydroxy-3,4-dimethyl-2H-chromen-2-one.

6,7-Dihydroxy-3,4-dimethyl-2H-chromen-2-one (CAS 16574-11-1) is a high-purity analytical reference standard with the molecular formula C11H10O4 and a molecular weight of 206.19 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 6,7-Dihydroxy-3,4-dimethyl-2H-chromen-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.19 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 6,7-Dihydroxy-3,4-dimethyl-2H-chromen-2-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.
