Description

Compared with other compounds in its class, the molecular weight of 211.22 g/mol gives 5-Phenylpyrazolo[1,5-a]pyrimidin-7(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Phenylpyrazolo[1,5-a]pyrimidin-7(4H)-one (CAS 29274-13-3) is a high-purity analytical reference standard with the molecular formula C12H9N3O and a molecular weight of 211.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Phenylpyrazolo[1,5-a]pyrimidin-7(4H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 211.22 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5-Phenylpyrazolo[1,5-a]pyrimidin-7(4H)-one 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.
