Description
As a certified reference material (CRM), 1-Chloro-3-(propane-2-sulfonyl)propane 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.
1-Chloro-3-(propane-2-sulfonyl)propane (CAS 128147-27-3), molecular formula C6H13ClO2S and molecular weight 184.68 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1-Chloro-3-(propane-2-sulfonyl)propane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.68 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.
