Chemical Structure

2-Chloroethyl methacrylate CAS 1888-94-4 chemical structure

Description

CATO manufactures 2-Chloroethyl methacrylate 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.

2-Chloroethyl methacrylate (CAS 1888-94-4), molecular formula C6H9ClO2 and molecular weight 148.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloroethyl methacrylate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.59 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.
