Chemical Structure

2-Methyl-1λ4-thiomorpholin-1-one CAS 1334146-71-2 chemical structure

Description

2-Methyl-1λ4-thiomorpholin-1-one (CAS 1334146-71-2), molecular formula C5H11NOS and molecular weight 133.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H11NOS, 2-Methyl-1λ4-thiomorpholin-1-one contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 133.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
