Chemical Structure

D-Ribitol-5-phosphate CAS 35320-17-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including D-Ribitol-5-phosphate.

D-Ribitol-5-phosphate (CAS 35320-17-3), molecular formula C5H13O8P and molecular weight 232.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, a phosphate ester group, D-Ribitol-5-phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
