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.
2-(3-Chlorobut-3-en-1-yl)-1,4-difluorobenzene (CAS 951892-27-6), molecular formula C10H9ClF2 and molecular weight 202.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine substitution, an aromatic ring system, 2-(3-Chlorobut-3-en-1-yl)-1,4-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-(3-Chlorobut-3-en-1-yl)-1,4-difluorobenzene 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.
