4-Amino-7-methyl-8-phenylpyrazolo[5,1-c][1,2,4]triazine-3-carbohydrazide CAS 1374509-33-7

Description

As a certified reference material (CRM), 4-Amino-7-methyl-8-phenylpyrazolo[5,1-c][1,2,4]triazine-3-carbohydrazide 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.

4-Amino-7-methyl-8-phenylpyrazolo[5,1-c][1,2,4]triazine-3-carbohydrazide (CAS 1374509-33-7) is a high-purity analytical reference standard with the molecular formula C13H13N7O and a molecular weight of 283.29 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Amino-7-methyl-8-phenylpyrazolo[5,1-c][1,2,4]triazine-3-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
