Chemical Structure

5-(1H-pyrazol-1-yl)pyrimidine CAS 934838-93-4 chemical structure

Description

As a certified reference material (CRM), 5-(1H-pyrazol-1-yl)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.

5-(1H-pyrazol-1-yl)pyrimidine (CAS 934838-93-4), molecular formula C7H6N4 and molecular weight 146.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(1H-pyrazol-1-yl)pyrimidine (C7H6N4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
