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.
1,4-Dichloro-2-butene cis & trans (CAS 764-41-0), molecular formula C4H6Cl2 and molecular weight 125.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, 1,4-Dichloro-2-butene cis & trans is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.00 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.
CATO manufactures 1,4-Dichloro-2-butene cis & trans 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.
