Chemical Structure

Diethyl meso-tartrate CAS 21066-72-8 chemical structure

Description

Diethyl meso-tartrate (C8H14O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

CATO supplies Diethyl meso-tartrate (CAS 21066-72-8), a certified reference material (molecular formula C8H14O6, MW 206.19 g/mol) for analytical method development and quality control.

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.
