Chemical Structure
Description
As a certified reference material (CRM), 1-(2,2-Difluoroethyl)-1H-pyrazol-5-amine 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.
1-(2,2-Difluoroethyl)-1H-pyrazol-5-amine (CAS 1171319-69-9), molecular formula C5H7F2N3 and molecular weight 147.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine substitution, 1-(2,2-Difluoroethyl)-1H-pyrazol-5-amine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 147.13 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.
