5-methyl-7-oxo-4H,7H-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile CAS 89975-58-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-methyl-7-oxo-4H,7H-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile.

5-methyl-7-oxo-4H,7H-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile (CAS 89975-58-6) is a high-purity analytical reference standard with the molecular formula C7H11N5O and a molecular weight of 181.20 g/mol.

The molecular framework of 5-methyl-7-oxo-4H,7H-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile (C7H11N5O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), 5-methyl-7-oxo-4H,7H-[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile 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.
