Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-4-(1-ethyl-5-methyl-1h-pyrazol-4-yl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide.
CATO supplies 3-Amino-4-(1-ethyl-5-methyl-1h-pyrazol-4-yl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (CAS 1005566-12-0), a certified reference material (molecular formula C15H14F3N5OS, MW 369.36 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 3-Amino-4-(1-ethyl-5-methyl-1h-pyrazol-4-yl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
