Chemical Structure
Description
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.
1-(Bromomethyl)-2-chloro-4-methylbenzene (CAS 868860-20-2), molecular formula C8H8BrCl and molecular weight 219.51 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Bromomethyl)-2-chloro-4-methylbenzene (C8H8BrCl) contains chlorine/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.
