Description
CATO manufactures 1-(3-Chlorobut-3-en-1-yl)-3-methylbenzene 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.
CATO supplies 1-(3-Chlorobut-3-en-1-yl)-3-methylbenzene (CAS 731772-17-1), a certified reference material (molecular formula C11H13Cl, MW 180.67 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Chlorobut-3-en-1-yl)-3-methylbenzene (C11H13Cl) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
