说明

一般描述

Ponceau SX is classified as a synthetic food color, widely used for the maintenance and improvement of color appearance in foods.[1]

应用

Ponceau SX may be used as a reference standard for the determination of the analyte:

• In cosmetic products by micro-matrix solid phase dispersion and liquid chromatography coupled to tandem mass spectrometry.[2]
• In foodstuffs by combining high performance liquid chromatography (HPLC) with diode array detection (DAD) and ion-trap time-of-flight mass spectrometry (IT-TOF/MS).[1]
