Chemical Structure
Description
As a certified reference material (CRM), 3-Amino-6-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Amino-6-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carbonitrile (CAS 317840-08-7), molecular formula C10H6F3N3S and molecular weight 257.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 3-Amino-6-methyl-4-(trifluoromethyl)thieno[2,3-b]pyridine-2-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.23 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.
