Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromomethyl-5-Methyl-benzo[b]thiophene.
CATO supplies 2-Bromomethyl-5-Methyl-benzo[b]thiophene (CAS 690632-71-4), a certified reference material (molecular formula C10H9BrS, MW 241.15 g/mol) for analytical method development and quality control.
2-Bromomethyl-5-Methyl-benzo[b]thiophene (C10H9BrS) contains sulfur-containing functionality, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
