Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Cyano-N-[(1E)-(dimethylamino)methylidene]-3-methyl-4-phenylthiophene-2-carboxamide (CAS 339111-53-4) is a high-purity analytical reference standard with the molecular formula C16H15N3OS and a molecular weight of 297.37 g/mol.
The molecular framework of 5-Cyano-N-[(1E)-(dimethylamino)methylidene]-3-methyl-4-phenylthiophene-2-carboxamide (C16H15N3OS) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
