Chemical Structure

cinnolin-8-amine CAS 21905-84-0 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.

cinnolin-8-amine (CAS 21905-84-0), molecular formula C8H17N3 and molecular weight 155.24 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H17N3, cinnolin-8-amine contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 155.24 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.

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.
