The journal of physical chemistry. A, 117(3), 642-649 (2013-01-08)
In this study, Raman, infrared, UV/vis, NMR, and single crystal X-ray diffraction spectroscopies are used to elucidate the tautomeric equilibrium of azo dyes derived from 1-phenyl-azo-2-naphthol (Sudan I). A new crystallographic structure is described for Sudan I, revealing the presence

Journal of agricultural and food chemistry, 60(1), 180-187 (2011-12-16)
A new single-hole hollow molecularly imprinted polymer (SHH-MIP) was prepared by multistep seed swelling polymerization using Sudan I as template molecule and successfully applied to selective solid-phase extraction (SPE) of Sudan dyes in chilli sauce samples. The polymers possessed high

Raman spectroscopy combined with multivariate analysis was evaluated as a tool for detecting Sudan I dye in culinary spices. Three Raman modalities were studied: normal Raman, FT-Raman and SERS. The results show that SERS is the most appropriate modality capable
Xiaofeng Yang et al.
Journal of AOAC International, 93(5), 1537-1541 (2010-12-15)
Rapid determination of Sudan I in foodstuffs is very important because it was found to be a carcinogen and its use in the food industry was banned. A rapid, sensitive, and convenient electrochemical method was developed for the determination of
