Chemical Structure

D-Erythrose - min 75% purity as a 70% aq. solution CAS 583-50-6 chemical structure

Description

The occurrence of D-Erythrose - min 75% purity as a 70% aq. solution is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

D-Erythrose - min 75% purity as a 70% aq. solution (CAS 583-50-6), molecular formula C4H8O4 and molecular weight 120.10 g/mol, is a CATO reference standard with documented purity and traceability.

D-Erythrose - min 75% purity as a 70% aq. solution (C4H8O4) 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.
