Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(But-3-en-1-yl)-4-chlorobenzene.
1-(But-3-en-1-yl)-4-chlorobenzene (CAS 3047-24-3), molecular formula C10H11Cl and molecular weight 166.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11Cl, 1-(But-3-en-1-yl)-4-chlorobenzene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 166.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 1-(But-3-en-1-yl)-4-chlorobenzene 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.
