Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((6-Chloro-9H-purin-9-yl)methyl)benzenesulfonamide.
CATO supplies 4-((6-Chloro-9H-purin-9-yl)methyl)benzenesulfonamide (CAS 21267-95-8), a certified reference material (molecular formula C12H10ClN5O2S, MW 323.76 g/mol) for analytical method development and quality control.
4-((6-Chloro-9H-purin-9-yl)methyl)benzenesulfonamide (C12H10ClN5O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-((6-Chloro-9H-purin-9-yl)methyl)benzenesulfonamide 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.
