Chemical Structure
Description
As a certified reference material (CRM), 6-Bromo-2,3-dihydro-4H-benzo[e][1,3]thiazin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
6-Bromo-2,3-dihydro-4H-benzo[e][1,3]thiazin-4-one (CAS 1411982-58-5), molecular formula C8H6BrNOS and molecular weight 244.11 g/mol, is a CATO reference standard with documented purity and traceability.
6-Bromo-2,3-dihydro-4H-benzo[e][1,3]thiazin-4-one (C8H6BrNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
