Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.36 g/mol gives Diethyl 2-(bis(methylthio)methylene)malonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diethyl 2-(bis(methylthio)methylene)malonate (CAS 55084-15-6), molecular formula C10H16O4S2 and molecular weight 264.36 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, Diethyl 2-(bis(methylthio)methylene)malonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.36 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-(bis(methylthio)methylene)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.
