Chemical Structure

Pyrazolo[1,5-c]pyrimidine CAS 274-57-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 119.12 g/mol gives Pyrazolo[1,5-c]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pyrazolo[1,5-c]pyrimidine (CAS 274-57-7), a certified reference material (molecular formula C6H5N3, MW 119.12 g/mol) for analytical method development and quality control.

The molecular framework of Pyrazolo[1,5-c]pyrimidine (C6H5N3) is characterized by a nitrile group, an aromatic ring system. 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.

As a certified reference material (CRM), Pyrazolo[1,5-c]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.
