Chemical Structure

2-aminopropane-1-thiol hydrochloride CAS 4145-98-6 chemical structure

Description

Structurally, 2-aminopropane-1-thiol hydrochloride (C3H9NSHCl) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 127.63 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-aminopropane-1-thiol hydrochloride (CAS 4145-98-6), molecular formula C3H9NSHCl and molecular weight 127.63 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.
