Chemical Structure
Description
5-ethyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-4-amine hydrochloride (CAS 1787909-27-6), molecular formula C12H12F3N3HCl and molecular weight 291.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 5-ethyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-4-amine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 5-ethyl-1-[3-(trifluoromethyl)phenyl]-1H-pyrazol-4-amine hydrochloride 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.
