Description
CATO manufactures 5-Amino-2-chloropyrimidin-4-ol 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.
5-Amino-2-chloropyrimidin-4-ol (CAS 1353777-47-5) is a high-purity analytical reference standard with the molecular formula C4H4ClN3O and a molecular weight of 145.55 g/mol.
5-Amino-2-chloropyrimidin-4-ol (C4H4ClN3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
