4-(Bromomethyl)-7-hydroxy-2H-chromen-2-one CAS 161798-25-0

Description

Compared with other compounds in its class, the molecular weight of 255.06 g/mol gives 4-(Bromomethyl)-7-hydroxy-2H-chromen-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Bromomethyl)-7-hydroxy-2H-chromen-2-one (CAS 161798-25-0), a certified reference material (molecular formula C10H7BrO3, MW 255.06 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 4-(Bromomethyl)-7-hydroxy-2H-chromen-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4-(Bromomethyl)-7-hydroxy-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.
