Chemical Structure
Description
The occurrence of 2-Bromo-4,5-dimethylbenzenethiol is closely related to sulfur-containing functionality, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-4,5-dimethylbenzenethiol (CAS 1263376-02-8), molecular formula C8H9BrS and molecular weight 217.13 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-4,5-dimethylbenzenethiol (C8H9BrS) contains sulfur-containing functionality, 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.
CATO manufactures 2-Bromo-4,5-dimethylbenzenethiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
