Description
CATO manufactures 4-Bromo-3-methylaniline hydrochloride 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.
4-Bromo-3-methylaniline hydrochloride (CAS 202925-03-9) is a high-purity analytical reference standard with the molecular formula C7H8BrNHCl and a molecular weight of 222.51 g/mol.
Based on its molecular formula C7H8BrNHCl, 4-Bromo-3-methylaniline hydrochloride contains a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
