N-(2-Mercaptoethyl)acetamide CAS 1190-73-4

Description

The occurrence of N-(2-Mercaptoethyl)acetamide 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.

N-(2-Mercaptoethyl)acetamide (CAS 1190-73-4), molecular formula C4H9NOS and molecular weight 119.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Mercaptoethyl)acetamide (C4H9NOS) is characterized by an amide group, sulfur-containing functionality, 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.

As a certified reference material (CRM), N-(2-Mercaptoethyl)acetamide 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.
