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 Diethyl Malonate-13C3.
CATO supplies Diethyl Malonate-13C3 (CAS 53051-81-3), a certified reference material (molecular formula C4[13C]3H12O4, MW 163.15 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, Diethyl Malonate-13C3 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 163.15 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.
