3,5-Dibromo-4-methylphenol CAS 13979-81-2

Description

Compared with other compounds in its class, the molecular weight of 265.93 g/mol gives 3,5-Dibromo-4-methylphenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Dibromo-4-methylphenol (CAS 13979-81-2), molecular formula C7H6Br2O and molecular weight 265.93 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3,5-Dibromo-4-methylphenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3,5-Dibromo-4-methylphenol 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.
