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 2-(1,3-Dimethylbutyl)propanedioic Acid 1,3-Diethyl Ester.
CATO supplies 2-(1,3-Dimethylbutyl)propanedioic Acid 1,3-Diethyl Ester (CAS 249728-64-1), a certified reference material (molecular formula C13H24O4, MW 244.33 g/mol) for analytical method development and quality control.
Structurally, 2-(1,3-Dimethylbutyl)propanedioic Acid 1,3-Diethyl Ester (C13H24O4) 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 244.33 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
