Pyrimido[4,5-g]quinazoline CAS 260-75-3 chemical structure

Description

CATO manufactures Pyrimido[4,5-g]quinazoline 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.

Pyrimido[4,5-g]quinazoline (CAS 260-75-3) is a high-purity analytical reference standard with the molecular formula C10H6N4 and a molecular weight of 182.18 g/mol.

Pyrimido[4,5-g]quinazoline (C10H6N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
