7-Methyl-2-(methylthio)-7H-purin-6-amine CAS 102169-59-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methyl-2-(methylthio)-7H-purin-6-amine.

7-Methyl-2-(methylthio)-7H-purin-6-amine (CAS 102169-59-5), molecular formula C7H9N5S and molecular weight 195.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 7-Methyl-2-(methylthio)-7H-purin-6-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.24 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.

As a certified reference material (CRM), 7-Methyl-2-(methylthio)-7H-purin-6-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
