Chemical Structure

L-Threonine-d2 CAS 1202936-45-5 chemical structure

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 L-Threonine-d2 (CAS 1202936-45-5), a certified reference material (molecular formula C4H7D2NO3, MW 121.13 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, L-Threonine-d2 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 121.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
