Chemical Structure

L-Threose (~0.2 M in Water) CAS 95-44-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 120.10 g/mol gives L-Threose (~0.2 M in Water) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

L-Threose (~0.2 M in Water) (CAS 95-44-3) is a high-purity analytical reference standard with the molecular formula C4H8O4 and a molecular weight of 120.10 g/mol.

L-Threose (~0.2 M in Water) (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.
