Description
CATO supplies 3,6-Dicyclopropyl-1-(2-fluorophenyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 1018164-66-3), a certified reference material (molecular formula C19H16FN3O2, MW 337.35 g/mol) for analytical method development and quality control.
Structurally, 3,6-Dicyclopropyl-1-(2-fluorophenyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid (C19H16FN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 337.35 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), 3,6-Dicyclopropyl-1-(2-fluorophenyl)-1h-pyrazolo[3,4-b]pyridine-4-carboxylic acid 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.
