Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-Dichloro-9-Nitroso-9H-Purine (CAS 2514773-56-7) is a high-purity analytical reference standard with the molecular formula C5HCl2N5O and a molecular weight of 218.00 g/mol.
The molecular framework of 2,6-Dichloro-9-Nitroso-9H-Purine (C5HCl2N5O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2,6-Dichloro-9-Nitroso-9H-Purine 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.
