Chemical Structure

2-((2-Amino-9-butyl-9H-purin-6-yl)thio)acetic acid CAS 91338-67-9 chemical structure

Description

The molecular framework of 2-((2-Amino-9-butyl-9H-purin-6-yl)thio)acetic acid (C11H15N5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

2-((2-Amino-9-butyl-9H-purin-6-yl)thio)acetic acid (CAS 91338-67-9), molecular formula C11H15N5O2S and molecular weight 281.33 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
