Chemical Structure

5-(Bromomethyl)isoxazol-3(2H)-one CAS 83014-80-6 chemical structure

Description

The occurrence of 5-(Bromomethyl)isoxazol-3(2H)-one is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(Bromomethyl)isoxazol-3(2H)-one (CAS 83014-80-6) is a high-purity analytical reference standard with the molecular formula C4H4BrNO2 and a molecular weight of 177.98 g/mol.

The molecular framework of 5-(Bromomethyl)isoxazol-3(2H)-one (C4H4BrNO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-(Bromomethyl)isoxazol-3(2H)-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.
