Description

CATO manufactures 2-BROMO-4-CYANOTOLUENE 3-BROMO-4-METHYLBENZENECARBONITRILE 3-BROMO-4-METHYLBENZONITRILE 4-METHYL-3-BROMOBENZONITRILE 42872-74-2 BC003584 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.

CATO supplies 2-BROMO-4-CYANOTOLUENE 3-BROMO-4-METHYLBENZENECARBONITRILE 3-BROMO-4-METHYLBENZONITRILE 4-METHYL-3-BROMOBENZONITRILE 42872-74-2 BC003584 (CAS 42872-74-2), a certified reference material (molecular formula C8H12BrN, MW 202.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H12BrN, 2-BROMO-4-CYANOTOLUENE 3-BROMO-4-METHYLBENZENECARBONITRILE 3-BROMO-4-METHYLBENZONITRILE 4-METHYL-3-BROMOBENZONITRILE 42872-74-2 BC003584 contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
