7-(2,4-Dimethylphenyl)-3-(pyridin-4-yl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine CAS 844647-18-3

Description

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.

7-(2,4-Dimethylphenyl)-3-(pyridin-4-yl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine (CAS 844647-18-3) is a high-purity analytical reference standard with the molecular formula C19H15N7 and a molecular weight of 341.37 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 7-(2,4-Dimethylphenyl)-3-(pyridin-4-yl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures 7-(2,4-Dimethylphenyl)-3-(pyridin-4-yl)-7H-pyrazolo[4,3-e][1,2,4]triazolo[4,3-c]pyrimidine 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.
