Chemical Structure
Description
As a certified reference material (CRM), 6-Methyl-isoquinoline-5-sulfonyl chloride 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.
CATO supplies 6-Methyl-isoquinoline-5-sulfonyl chloride (CAS 949109-33-5), a certified reference material (molecular formula C10H8ClNO2S, MW 241.69 g/mol) for analytical method development and quality control.
6-Methyl-isoquinoline-5-sulfonyl chloride (C10H8ClNO2S) 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. 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.
