Description

The occurrence of L9AL2GO03Y 637-53-6 Thioacetanilide Acetanilide, thio- Ethanethioamide, N-phenyl- 4-12-00-00378 (Beilstein Handbook Reference) AI3-00235 BRN 2205727 EINECS 211-288-4 NSC 36984 N-Phenylthioacetamide USAF EK-1902 UNII-L9AL2GO03Y is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

L9AL2GO03Y 637-53-6 Thioacetanilide Acetanilide, thio- Ethanethioamide, N-phenyl- 4-12-00-00378 (Beilstein Handbook Reference) AI3-00235 BRN 2205727 EINECS 211-288-4 NSC 36984 N-Phenylthioacetamide USAF EK-1902 UNII-L9AL2GO03Y (CAS 637-53-6) is a high-purity analytical reference standard with the molecular formula C8H15NS and a molecular weight of 157.28 g/mol.

The molecular framework of L9AL2GO03Y 637-53-6 Thioacetanilide Acetanilide, thio- Ethanethioamide, N-phenyl- 4-12-00-00378 (Beilstein Handbook Reference) AI3-00235 BRN 2205727 EINECS 211-288-4 NSC 36984 N-Phenylthioacetamide USAF EK-1902 UNII-L9AL2GO03Y (C8H15NS) is characterized by a nitrile group, sulfur-containing functionality. 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.

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.
