Chemical Structure

D-Threitol 99% CAS 7493-90-5 chemical structure

Description

D-Threitol 99% (CAS 7493-90-5), molecular formula C4H10O4 and molecular weight 122.12 g/mol, is a CATO reference standard with documented purity and traceability.

D-Threitol 99% (C4H10O4) 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
