Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,8-Bis(methylthio)-9H-purine.
2,8-Bis(methylthio)-9H-purine (CAS 10179-95-0), molecular formula C7H8N4S2 and molecular weight 212.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H8N4S2, 2,8-Bis(methylthio)-9H-purine contains a nitrile group, sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
