Description
CATO manufactures 2-Chloro-4-(piperidin-1-yl)pteridine 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.
2-Chloro-4-(piperidin-1-yl)pteridine (CAS 1429903-11-6), molecular formula C11H12ClN5 and molecular weight 249.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-4-(piperidin-1-yl)pteridine (C11H12ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
