Chemical Structure

4-Amino-2',3-dimethylazobenzene CAS 97-56-3 chemical structure

Description

As a certified reference material (CRM), 4-Amino-2',3-dimethylazobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-Amino-2',3-dimethylazobenzene (CAS 97-56-3) is a high-purity analytical reference standard with the molecular formula C14H15N3 and a molecular weight of 225.29 g/mol.

Based on its molecular formula C14H15N3, 4-Amino-2',3-dimethylazobenzene contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 225.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
