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 Dimethyl 2-(Methoxymethylene)malonate.
Dimethyl 2-(Methoxymethylene)malonate (CAS 22398-14-7), molecular formula C7H10O5 and molecular weight 174.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dimethyl 2-(Methoxymethylene)malonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.15 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), Dimethyl 2-(Methoxymethylene)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.
