5-(3-Methoxyphenyl)-2-methyl-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine CAS 680199-98-8

Description

5-(3-Methoxyphenyl)-2-methyl-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (CAS 680199-98-8) is a high-purity analytical reference standard with the molecular formula C15H12F3N3O and a molecular weight of 307.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 5-(3-Methoxyphenyl)-2-methyl-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.27 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.

As a certified reference material (CRM), 5-(3-Methoxyphenyl)-2-methyl-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine 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.
