Description
898772-47-9 5-Chloro-1-[5-(1,3-dioxolan-2-yl)thiophen-2-yl]pentan-1-one DTXSID80641894 (CAS 898772-47-9), molecular formula C12H15ClO3S and molecular weight 274.76 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, an aromatic ring system, 898772-47-9 5-Chloro-1-[5-(1,3-dioxolan-2-yl)thiophen-2-yl]pentan-1-one DTXSID80641894 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 898772-47-9 5-Chloro-1-[5-(1,3-dioxolan-2-yl)thiophen-2-yl]pentan-1-one DTXSID80641894 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.
