Chemical Structure
Description
As a certified reference material (CRM), 4-Methyl-5-[3-(trifluoromethyl)-1h-pyrazol-1-yl]-1,3-thiazol-2-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.
4-Methyl-5-[3-(trifluoromethyl)-1h-pyrazol-1-yl]-1,3-thiazol-2-amine (CAS 1006348-68-0) is a high-purity analytical reference standard with the molecular formula C8H7F3N4S and a molecular weight of 248.23 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 4-Methyl-5-[3-(trifluoromethyl)-1h-pyrazol-1-yl]-1,3-thiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
