Chemical Structure
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-Bromopyrido[3,2-d]pyrimidin-2-amine (CAS 1935306-50-5), molecular formula C7H5BrN4 and molecular weight 225.05 g/mol, is a CATO reference standard with documented purity and traceability.
7-Bromopyrido[3,2-d]pyrimidin-2-amine (C7H5BrN4) contains a nitrile group, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 7-Bromopyrido[3,2-d]pyrimidin-2-amine 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.
