7-Chloro-5-phenylpyrazolo[1,5-a]pyrimidine CAS 33149-25-6

Description

The occurrence of 7-Chloro-5-phenylpyrazolo[1,5-a]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 7-Chloro-5-phenylpyrazolo[1,5-a]pyrimidine (CAS 33149-25-6), a certified reference material (molecular formula C12H8ClN3, MW 229.67 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-Chloro-5-phenylpyrazolo[1,5-a]pyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 229.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 7-Chloro-5-phenylpyrazolo[1,5-a]pyrimidine 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.
