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-methyl-1-(trifluoromethyl)benzene.
2-Bromo-4-methyl-1-(trifluoromethyl)benzene (CAS 121793-12-2) is a high-purity analytical reference standard with the molecular formula C8H6BrF3 and a molecular weight of 239.03 g/mol.
2-Bromo-4-methyl-1-(trifluoromethyl)benzene (C8H6BrF3) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
