Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl 2-(1,1-dioxidotetrahydrothiophen-3-yl)malonate.
CATO supplies Diethyl 2-(1,1-dioxidotetrahydrothiophen-3-yl)malonate (CAS 4785-62-0), a certified reference material (molecular formula C11H18O6S, MW 278.32 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 2-(1,1-dioxidotetrahydrothiophen-3-yl)malonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Diethyl 2-(1,1-dioxidotetrahydrothiophen-3-yl)malonate 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.
