Chemical Structure

Cis-1,2-Dichloroethene CAS 156-59-2 chemical structure

Description

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.

Cis-1,2-Dichloroethene (CAS 156-59-2) is a high-purity analytical reference standard with the molecular formula C2H2Cl2 and a molecular weight of 96.94 g/mol.

The molecular framework of Cis-1,2-Dichloroethene (C2H2Cl2) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Cis-1,2-Dichloroethene 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.
