Chemical Structure

Isosaccharinic acid-1-4-lactone CAS 7397-89-9 chemical structure

Description

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

Isosaccharinic acid-1-4-lactone (CAS 7397-89-9) is a high-purity analytical reference standard with the molecular formula C6H10O5 and a molecular weight of 162.14 g/mol.

Owing to a carbohydrate-derived structure, Isosaccharinic acid-1-4-lactone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
