Cysteamine Impurity 2 CAS 51859-63-3

Description

The occurrence of Cysteamine Impurity 2 is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cysteamine Impurity 2 (CAS 51859-63-3), a certified reference material (molecular formula C4H9NOS, MW 119.19 g/mol) for analytical method development and quality control.

Cysteamine Impurity 2 (C4H9NOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.

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.
