Chemical Structure

Ribitol CAS 488-81-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 152.15 g/mol gives Ribitol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ribitol (CAS 488-81-3) is a high-purity analytical reference standard with the molecular formula C5H12O5 and a molecular weight of 152.15 g/mol.

Owing to a carbohydrate-derived structure, Ribitol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.15 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.

As a certified reference material (CRM), Ribitol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
