Chemical Structure
Description
5-chloro-7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 92146-30-0) is a high-purity analytical reference standard with the molecular formula C11H7ClN4 and a molecular weight of 230.65 g/mol.
5-chloro-7-phenyl-[1,2,4]triazolo[1,5-a]pyrimidine (C11H7ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 5-chloro-7-phenyl-[1,2,4]triazolo[1,5-a]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.
