Description

Compared with other compounds in its class, the molecular weight of 163.18 g/mol gives 3,5-Dimethylpyrazolo[1,5-a]pyrimidin-7-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Dimethylpyrazolo[1,5-a]pyrimidin-7-ol (CAS 2090978-79-1), molecular formula C8H9N3O and molecular weight 163.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,5-Dimethylpyrazolo[1,5-a]pyrimidin-7-ol (C8H9N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 3,5-Dimethylpyrazolo[1,5-a]pyrimidin-7-ol 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.
