Chemical Structure

1,2-Dichloroethylene, mixture of cis and trans CAS 540-59-0 chemical structure

Description

As a certified reference material (CRM), 1,2-Dichloroethylene, mixture of cis and trans 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.

CATO supplies 1,2-Dichloroethylene, mixture of cis and trans (CAS 540-59-0), a certified reference material (molecular formula C2H2Cl2, MW 96.94 g/mol) for analytical method development and quality control.

Based on its molecular formula C2H2Cl2, 1,2-Dichloroethylene, mixture of cis and trans contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 96.94 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
