Description
CATO manufactures 6-(Chloromethyl)pteridine-2,4-diamine 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.
6-(Chloromethyl)pteridine-2,4-diamine (CAS 57521-63-8), molecular formula C7H7ClN6 and molecular weight 210.62 g/mol, is a CATO reference standard with documented purity and traceability.
6-(Chloromethyl)pteridine-2,4-diamine (C7H7ClN6) contains a nitrile group, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
