Chemical Structure

L-Threonic acid-1-4-lactone CAS 21730-93-8 chemical structure

Description

CATO supplies L-Threonic acid-1-4-lactone (CAS 21730-93-8), a certified reference material (molecular formula C4H7NO3, MW 117.10 g/mol) for analytical method development and quality control.

The molecular framework of L-Threonic acid-1-4-lactone (C4H7NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), L-Threonic acid-1-4-lactone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
