Chemical Structure

L-Erythrono-1,4-lactone CAS 23732-40-3 chemical structure

Description

The occurrence of L-Erythrono-1,4-lactone is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

L-Erythrono-1,4-lactone (CAS 23732-40-3), molecular formula C4H6O4 and molecular weight 118.09 g/mol, is a CATO reference standard with documented purity and traceability.

L-Erythrono-1,4-lactone (C4H6O4) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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

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.
