Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (1,1-dioxido-2,3-dihydrothiophen-3-yl)carbamate.
CATO supplies Ethyl (1,1-dioxido-2,3-dihydrothiophen-3-yl)carbamate (CAS 55212-69-6), a certified reference material (molecular formula C7H11NO4S, MW 205.23 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl (1,1-dioxido-2,3-dihydrothiophen-3-yl)carbamate (C7H11NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Ethyl (1,1-dioxido-2,3-dihydrothiophen-3-yl)carbamate 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.
