Chemical Structure

2-(Isothiazol-5-yl)ethan-1-amine hydrochloride CAS 2089258-27-3 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.

CATO supplies 2-(Isothiazol-5-yl)ethan-1-amine hydrochloride (CAS 2089258-27-3), a certified reference material (molecular formula C5H8N2SHCl, MW 164.65 g/mol) for analytical method development and quality control.

2-(Isothiazol-5-yl)ethan-1-amine hydrochloride (C5H8N2SHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
