Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Diethyl 2-(3-methoxypropyl)malonate (CAS 137045-28-4), a certified reference material (molecular formula C11H20O5, MW 232.27 g/mol) for analytical method development and quality control.
Structurally, Diethyl 2-(3-methoxypropyl)malonate (C11H20O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 232.27 g/mol, it falls into the medium-molecular-weight range.
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.
