Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-N,4-dimethylaniline, HCl.
3-Bromo-N,4-dimethylaniline, HCl (CAS 1187386-24-8), molecular formula C8H10BrNHCl and molecular weight 236.54 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H10BrNHCl, 3-Bromo-N,4-dimethylaniline, HCl contains a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
