Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 238.12 g/mol gives 5-Bromo-2-isobutylbenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-isobutylbenzonitrile (CAS 856167-67-4), molecular formula C11H12BrN and molecular weight 238.12 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-isobutylbenzonitrile (C11H12BrN) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 5-Bromo-2-isobutylbenzonitrile 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.
