Chemical Structure

Bromomethane CAS 74-83-9 chemical structure

Description

The occurrence of Bromomethane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Bromomethane (CAS 74-83-9), a certified reference material (molecular formula CH3Br, MW 94.94 g/mol) for analytical method development and quality control.

Owing to bromine substitution, Bromomethane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 94.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 Bromomethane 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.
