Chemical Structure
Description
The occurrence of 6-Chloro-8-iodo-9-methyl-9H-purine is closely related to a nitrile group, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-8-iodo-9-methyl-9H-purine (CAS 932731-59-4), molecular formula C6H4ClIN4 and molecular weight 294.48 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/iodine substitution, an aromatic ring system, 6-Chloro-8-iodo-9-methyl-9H-purine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
CATO manufactures 6-Chloro-8-iodo-9-methyl-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.
