Chemical Structure

5-sulfopentanoic acid CAS 89211-38-1 chemical structure

Description

Structurally, 5-sulfopentanoic acid (C5H10O5S) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 182.19 g/mol, it falls into the medium-molecular-weight range.

5-sulfopentanoic acid (CAS 89211-38-1), molecular formula C5H10O5S and molecular weight 182.19 g/mol, is a CATO reference standard with documented purity and traceability.

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.
