Chemical Structure
Description
CATO supplies (Z)-1-Bromobut-1-ene (CAS 31849-78-2), a certified reference material (molecular formula C4H7Br, MW 135.00 g/mol) for analytical method development and quality control.
The molecular framework of (Z)-1-Bromobut-1-ene (C4H7Br) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (Z)-1-Bromobut-1-ene 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.
