Methyl 2-(7-hydroxy-4,8-dimethyl-2-oxo-2h-chromen-3-yl)acetate CAS 433703-81-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-(7-hydroxy-4,8-dimethyl-2-oxo-2h-chromen-3-yl)acetate.

Methyl 2-(7-hydroxy-4,8-dimethyl-2-oxo-2h-chromen-3-yl)acetate (CAS 433703-81-2) is a high-purity analytical reference standard with the molecular formula C14H14O5 and a molecular weight of 262.26 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Methyl 2-(7-hydroxy-4,8-dimethyl-2-oxo-2h-chromen-3-yl)acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.26 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), Methyl 2-(7-hydroxy-4,8-dimethyl-2-oxo-2h-chromen-3-yl)acetate 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.
