Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2E)-4-Bromobut-2-enenitrile, E (CAS 37590-23-1), molecular formula C4H4BrN and molecular weight 145.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-4-Bromobut-2-enenitrile, E (C4H4BrN) is characterized by a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (2E)-4-Bromobut-2-enenitrile, E 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.
