Chemical Structure
Description
The occurrence of 1,3,5-Tribromo-2-methylbenzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3,5-Tribromo-2-methylbenzene (CAS 6320-40-7), a certified reference material (molecular formula C7H5Br3, MW 328.83 g/mol) for analytical method development and quality control.
1,3,5-Tribromo-2-methylbenzene (C7H5Br3) contains 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.
