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-(2,2-dimethoxyethyl)malonate.
Dimethyl 2-(2,2-dimethoxyethyl)malonate (CAS 51534-81-7), molecular formula C9H16O6 and molecular weight 220.22 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-(2,2-dimethoxyethyl)malonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
