Chloroprene CAS 126-99-8 chemical structure

Description

CATO manufactures Chloroprene 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.

Chloroprene (CAS 126-99-8), molecular formula C4H5Cl and molecular weight 88.54 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, Chloroprene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 88.54 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.
