Chemical Structure

2-Aminopurine DiHCl CAS 76124-64-6 chemical structure

Description

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.

2-Aminopurine DiHCl (CAS 76124-64-6), molecular formula C5H5N5HCl and molecular weight 171.59 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Aminopurine DiHCl (C5H5N5HCl) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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