Chemical Structure

4-Pentyne-1-thiol (>90%) CAS 77213-88-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 100.18 g/mol gives 4-Pentyne-1-thiol (>90%) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Pentyne-1-thiol (>90%) (CAS 77213-88-8), a certified reference material (molecular formula C5H8S, MW 100.18 g/mol) for analytical method development and quality control.

Structurally, 4-Pentyne-1-thiol (>90%) (C5H8S) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 100.18 g/mol, it falls into the low-molecular-weight range.

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.
