Description
CATO supplies 6-Chloro-7-(3,5-dihydro-2H-benzo[e][1,4]oxathiepin-3-yl)-7H-purine (CAS 921929-78-4), a certified reference material (molecular formula C14H11ClN4OS, MW 318.78 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-7-(3,5-dihydro-2H-benzo[e][1,4]oxathiepin-3-yl)-7H-purine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 6-Chloro-7-(3,5-dihydro-2H-benzo[e][1,4]oxathiepin-3-yl)-7H-purine 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.
