Description

CATO manufactures 3-(4-Fluorophenyl)-6-(2-methylpropane-2-sulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

3-(4-Fluorophenyl)-6-(2-methylpropane-2-sulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine (CAS 865658-03-3), molecular formula C16H17FN4O2S and molecular weight 348.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 3-(4-Fluorophenyl)-6-(2-methylpropane-2-sulfonyl)pyrazolo[1,5-a]pyrimidin-7-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.40 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.
