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-(1-Bromopropan-2-ylidene)malononitrile (CAS 4651-79-0) is a high-purity analytical reference standard with the molecular formula C6H5BrN2 and a molecular weight of 185.02 g/mol.
The molecular framework of 2-(1-Bromopropan-2-ylidene)malononitrile (C6H5BrN2) is characterized by a nitrile group, bromine substitution, an aromatic ring system. 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 2-(1-Bromopropan-2-ylidene)malononitrile 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.
