Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 210.07 g/mol gives 2-Bromo-4-methylphenylacetonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-4-methylphenylacetonitrile (CAS 1069114-80-2), molecular formula C9H8BrN and molecular weight 210.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4-methylphenylacetonitrile (C9H8BrN) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
