Chemical Structure

2-Methylthio-N6-isopentenylasenine CAS 20758-33-2 chemical structure

Description

2-Methylthio-N6-isopentenylasenine (CAS 20758-33-2) is a high-purity analytical reference standard with the molecular formula C11H15N5S and a molecular weight of 249.34 g/mol.

Structurally, 2-Methylthio-N6-isopentenylasenine (C11H15N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 249.34 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
