Chemical Structure
Description
Trans-1,2-Dichloroethene (CAS 156-60-5), molecular formula C2H2Cl2 and molecular weight 96.94 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Trans-1,2-Dichloroethene (C2H2Cl2) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 96.94 g/mol, it falls into the low-molecular-weight range. 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.
As a certified reference material (CRM), Trans-1,2-Dichloroethene 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.
