Chemical Structure

4,6-Dibromoisochroman-1-one CAS 1374573-99-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 305.95 g/mol gives 4,6-Dibromoisochroman-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,6-Dibromoisochroman-1-one (CAS 1374573-99-5) is a high-purity analytical reference standard with the molecular formula C9H6Br2O2 and a molecular weight of 305.95 g/mol.

The molecular framework of 4,6-Dibromoisochroman-1-one (C9H6Br2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 4,6-Dibromoisochroman-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
