Chemical Structure
Description
(5-Chlorobenzo[d]thiazol-2-yl)methyl 4-methylbenzenesulfonate (C15H12ClNO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
(5-Chlorobenzo[d]thiazol-2-yl)methyl 4-methylbenzenesulfonate (CAS 100865-43-8) is a high-purity analytical reference standard with the molecular formula C15H12ClNO3S2 and a molecular weight of 353.84 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (5-Chlorobenzo[d]thiazol-2-yl)methyl 4-methylbenzenesulfonate 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.
