Chemical Structure

2-((2-Aminoethyl)thio)acetic acid CAS 3335-52-2 chemical structure

Description

As a certified reference material (CRM), 2-((2-Aminoethyl)thio)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

2-((2-Aminoethyl)thio)acetic acid (CAS 3335-52-2) is a high-purity analytical reference standard with the molecular formula C4H9NO2S and a molecular weight of 135.18 g/mol.

The molecular framework of 2-((2-Aminoethyl)thio)acetic acid (C4H9NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
