N-Methyl-2-(quinoxalin-2-ylsulfanyl)acetamide CAS 338394-75-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Methyl-2-(quinoxalin-2-ylsulfanyl)acetamide.

N-Methyl-2-(quinoxalin-2-ylsulfanyl)acetamide (CAS 338394-75-5), molecular formula C11H11N3OS and molecular weight 233.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-Methyl-2-(quinoxalin-2-ylsulfanyl)acetamide (C11H11N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 233.29 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
