Description

Compared with other compounds in its class, the molecular weight of 243.72 g/mol gives 9-(2-Chloroethyl)-6-(methylthio)-9H-purin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9-(2-Chloroethyl)-6-(methylthio)-9H-purin-2-amine (CAS 2879-78-9), molecular formula C8H10ClN5S and molecular weight 243.72 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 9-(2-Chloroethyl)-6-(methylthio)-9H-purin-2-amine (C8H10ClN5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
