Description
As a certified reference material (CRM), 3-Chloro-5-(pyrrolidin-1-ylsulfonyl)pyridine-4-thiol 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 3-Chloro-5-(pyrrolidin-1-ylsulfonyl)pyridine-4-thiol (CAS 1352507-28-8), a certified reference material (molecular formula C9H11ClN2O2S2, MW 278.78 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-5-(pyrrolidin-1-ylsulfonyl)pyridine-4-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.78 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.
