Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-4-nitro-1-(trifluoromethyl)benzene.
2-Bromo-4-nitro-1-(trifluoromethyl)benzene (CAS 875238-74-7) is a high-purity analytical reference standard with the molecular formula C7H3BrF3NO2 and a molecular weight of 270.00 g/mol.
Based on its molecular formula C7H3BrF3NO2, 2-Bromo-4-nitro-1-(trifluoromethyl)benzene contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.00 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.
CATO manufactures 2-Bromo-4-nitro-1-(trifluoromethyl)benzene 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.
