Chemical Structure

Diethyl 2-hydroxy-3-methylsuccinate CAS 93504-92-8 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 2-hydroxy-3-methylsuccinate.

CATO supplies Diethyl 2-hydroxy-3-methylsuccinate (CAS 93504-92-8), a certified reference material (molecular formula C9H16O5, MW 204.22 g/mol) for analytical method development and quality control.

Structurally, Diethyl 2-hydroxy-3-methylsuccinate (C9H16O5) 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 204.22 g/mol, it falls into the medium-molecular-weight range.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
