Chemical Structure

2-Ethylthiomorpholine-4-carbaldehyde CAS 30188-23-9 chemical structure

Description

The molecular framework of 2-Ethylthiomorpholine-4-carbaldehyde (C7H13NOS) 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.

2-Ethylthiomorpholine-4-carbaldehyde (CAS 30188-23-9) is a high-purity analytical reference standard with the molecular formula C7H13NOS and a molecular weight of 159.25 g/mol.

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.
