Description
As a certified reference material (CRM), 5-Bromo-4-methoxy-1,3-benzothiazol-2-amine 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.
5-Bromo-4-methoxy-1,3-benzothiazol-2-amine (CAS 1359829-20-1), molecular formula C8H7BrN2OS and molecular weight 259.12 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-4-methoxy-1,3-benzothiazol-2-amine (C8H7BrN2OS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
