General description
Sudan dyes are classified under the azo dyes group of organic compounds that are commonly utilized as additive materials for industrial and scientific applications.
Application
Sudan red G may be used for the identification of sudan red G in:
- Food samples by hydrazone linked covalent organic polymer (HL-COP) based micro-solid phase extraction (μ-SPE) combined with high performance liquid chromatography (HPLC) with ultraviolet (UV) detection.
- Chili powders and syrup-preserved fruits by LC coupled to electrospray ionization tandem mass spectrometry (ESI-MS/MS) with multiple reaction monitoring (MRM) mode of detection.
- Chili products by HPLC combined with gel permeation chromatography (GPC) clean-up method as well as HPLC coupled to diode array detector (DAD) with multiple wavelength detection capability.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
