Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Bromo-8-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalene.
5-Bromo-8-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalene (CAS 2128284-74-0), molecular formula C11H10BrF3 and molecular weight 279.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/bromine substitution, an aromatic ring system, 5-Bromo-8-(trifluoromethyl)-1,2,3,4-tetrahydronaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
