The occurrence of Cis-1,4-Dichloro-2-Butene is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cis-1,4-Dichloro-2-Butene (CAS 1476-11-5), a certified reference material (molecular formula C4H6Cl2, MW 125.00 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H6Cl2, Cis-1,4-Dichloro-2-Butene contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 125.00 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.
As a certified reference material (CRM), Cis-1,4-Dichloro-2-Butene 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.
