Chemical Structure
Description
4,5-Dichloropyrimidin-2-amine (CAS 403854-21-7), molecular formula C4H3Cl2N3 and molecular weight 163.99 g/mol, is a CATO reference standard with documented purity and traceability.
4,5-Dichloropyrimidin-2-amine (C4H3Cl2N3) contains a nitrile group, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,5-Dichloropyrimidin-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.
