Chemical Structure
Description
N-(2-(3-(Pyridin-2-yl)-1H-pyrazol-1-yl)ethyl)thiophene-2-carboxamide (C15H14N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
N-(2-(3-(Pyridin-2-yl)-1H-pyrazol-1-yl)ethyl)thiophene-2-carboxamide (CAS 1448071-70-2), molecular formula C15H14N4OS and molecular weight 298.36 g/mol, is a CATO reference standard with documented purity and traceability.
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.
