7-Methyl-3-(thiophene-2-carbonyl)-4H-chromen-4-one CAS 309923-38-4

Description

The occurrence of 7-Methyl-3-(thiophene-2-carbonyl)-4H-chromen-4-one is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Methyl-3-(thiophene-2-carbonyl)-4H-chromen-4-one (CAS 309923-38-4), molecular formula C15H10O3S and molecular weight 270.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Methyl-3-(thiophene-2-carbonyl)-4H-chromen-4-one (C15H10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 7-Methyl-3-(thiophene-2-carbonyl)-4H-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.
