Description

General description

Metanil Yellow (MY) belongs to the azo group of dyes.

Application

Metanil Yellow (MY) may be used as an analytical reference standard for the determination of MY in:

• Lipsticks and eye shadows by microwave-assisted dispersive liquid-liquid microextraction (MA-DLLME) using solidification of the floating organic droplet (SFOD) clean-up followed by analysis using high performance liquid chromatography-diode array detection (HPLC-DAD).
• Ball-point pen ink, in paper ink and in turmeric raw materials as well as finished products by HPLC-DAD.
