Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((6-Methylthieno[2,3-d]pyrimidin-4-yl)thio)-N-(o-tolyl)acetamide.
2-((6-Methylthieno[2,3-d]pyrimidin-4-yl)thio)-N-(o-tolyl)acetamide (CAS 878696-58-3) is a high-purity analytical reference standard with the molecular formula C16H15N3OS2 and a molecular weight of 329.44 g/mol.
The molecular framework of 2-((6-Methylthieno[2,3-d]pyrimidin-4-yl)thio)-N-(o-tolyl)acetamide (C16H15N3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
