Chemical Structure
Description
1-Bromo-3-(propane-2-sulfinyl)benzene (CAS 1345471-26-2), molecular formula C9H11BrOS and molecular weight 247.15 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-3-(propane-2-sulfinyl)benzene (C9H11BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Bromo-3-(propane-2-sulfinyl)benzene 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.
