Chemical Structure

S-Methyl Thiobutyrate CAS 2432-51-1 chemical structure

Description

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.

S-Methyl Thiobutyrate (CAS 2432-51-1), molecular formula C5H10OS and molecular weight 118.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, S-Methyl Thiobutyrate (C5H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 118.20 g/mol, it falls into the low-molecular-weight range.

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.
