3-Chloro-5-methyl-2-(1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine CAS 956782-01-7

Description

3-Chloro-5-methyl-2-(1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-7-(trifluoromethyl)pyrazolo[1,5-a]pyrimidine (CAS 956782-01-7), molecular formula C13H8ClF6N5 and molecular weight 383.68 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, 3-Chloro-5-methyl-2-(1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-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 383.68 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), 3-Chloro-5-methyl-2-(1-methyl-5-(trifluoromethyl)-1H-pyrazol-4-yl)-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.
