CATO supplies Diethyl 2,3-O-isopropylidene-L-tartrate (CAS 59779-75-8), a certified reference material (molecular formula C11H18O6, MW 246.26 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 2,3-O-isopropylidene-L-tartrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Diethyl 2,3-O-isopropylidene-L-tartrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
