Chemical Structure

2-(Chloromethyl)oxazole-4-carbaldehyde CAS 154136-85-3 chemical structure

Description

The occurrence of 2-(Chloromethyl)oxazole-4-carbaldehyde is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(Chloromethyl)oxazole-4-carbaldehyde (CAS 154136-85-3) is a high-purity analytical reference standard with the molecular formula C5H4ClNO2 and a molecular weight of 145.54 g/mol.

2-(Chloromethyl)oxazole-4-carbaldehyde (C5H4ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-(Chloromethyl)oxazole-4-carbaldehyde 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.
