Chemical Structure
Description
2,3-Dichloro-1-Propene (CAS 78-88-6), molecular formula C3H4Cl2 and molecular weight 110.97 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C3H4Cl2, 2,3-Dichloro-1-Propene contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 110.97 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.
CATO manufactures 2,3-Dichloro-1-Propene 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.
