Toxicity of an imported fire ant bait based on phloxin B (D + C Red 27): Toxicity of an imported fire ant bait based on phloxin B (D + C Red 27). David, Robert M.; Heitz, James R. (Mississippi Agric. For. Exp. Stn., Mississippi State Univ., Mississippi State, Miss., USA). J. Agric. Food Chem., 26(1), 99-101 (English) 1978. CODEN: JAFCAU. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Laboratory tests have shown that incorporation of D and C Red 27 (Phloxin B)(I) [13473-26-2] into a soybean oil-corn cob grit bait yielded an efficient toxicant for the imported fire ant (Solenopsis richteri). I induces 2 lethal mechanisms within the imported fire ant: the 1st is light dependent and is effective in terms of h; the 2nd is light independent and is effective in terms of days. The relatively rapid light-dependent reaction is obsd. after a 1-day pretreatment which indicates that the reaction will not interfere with field collection of the bait by worker ants. Both toxic mechanisms were more pronounced in insects subjected to a slight energy stress caused by food deprivation.

Quantitative analysis of components of the color additives D&C Red Nos: Quantitative analysis of components of the color additives D&C Red Nos. 27 and 28 (phloxine B) by thin-layer chromatography and video densitometry. Wright, Pamela R.; Richfield-Fratz, Naomi; Rasooly, Avraham; Weisz, Adrian (Office of Cosmetics and Colors, US Food and Drug Administration, Washington, DC 20204, USA). Journal of Planar Chromatography--Modern TLC, 10(3), 157-162 (English) 1997 Research Institute for Medicinal Plants.Chemical with cas number 13473-26-2 also plays role. CODEN: JPCTE5. ISSN: 0933-4173. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 17 A simple and rapid TLC/videodensitometric method has been developed for the in-situ quantification either of lower halogenated subsidiary colors (LHSC) or of the Et ester (EE) in multiple dye samples on the same anal. TLC plate. The results obtained by this method were compared with those obtained by an indirect TLC/spectrophotometric method and those obtained by HPLC. The total time for the TLC/videodensitometric assay of five stds. 13473-26-2 which is the cas registry number of some chemical is mentioned. and four samples applied to each plate was 45 min or less. This method for the detn. of LHSC and EE in D&C Red Nos. 27 and 28 was found to be applicable for use in routine batch-certification anal. ..
