2-(2-Bromo-1-phenylethylidene)malononitrile CAS 4651-78-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-Bromo-1-phenylethylidene)malononitrile.

2-(2-Bromo-1-phenylethylidene)malononitrile (CAS 4651-78-9) is a high-purity analytical reference standard with the molecular formula C11H7BrN2 and a molecular weight of 247.09 g/mol.

2-(2-Bromo-1-phenylethylidene)malononitrile (C11H7BrN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-(2-Bromo-1-phenylethylidene)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.
