  • Benzyl Chloride)
    Screening Assessment for the Challenge Benzene, (chloromethyl)- (Benzyl chloride) Chemical Abstracts Service Registry Number 100-44-7 Environment Canada Health Canada November 2009 Screening Assessment CAS RN 100-44-7 Synopsis Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment of benzene, (chloromethyl)-, also known as benzyl chloride, Chemical Abstracts Service Registry Number 100-44-7. This substance was identified in the categorization of the Domestic Substances List (DSL) as a high priority for action under the Challenge. Benzyl chloride was identified as presenting greatest potential for exposure of individuals in Canada and had been classified by other agencies on the basis of carcinogenicity and genotoxicity. Although the substance met the categorization criteria for persistence, it did not meet the criteria for bioaccumulation potential or inherent toxicity to aquatic organisms; therefore, the focus of this assessment relates primarily to human health aspects. According to data submitted in response to a Notice issued under section 71 of the Act, no persons in Canada reported manufacturing benzyl chloride in a quantity greater than or equal to the reporting threshold of 100 kg for the 2006 calendar year. However, it was reported that 100 000–1 000 000 kg were imported into Canada in that year. The response to the section 71 notice indicated that benzyl chloride is mainly used in Canada as a chemical intermediate for the synthesis of quaternary ammonium compounds, which are used primarily as hard surface sanitizers, corrosion inhibitors, fungicides in industrial cleaners and bactericides in surfactants in household and personal care products.

  • Important Interactions in Peptide-Based Transfection Agents, Sugars As Chiral Scaffolds, and Molecular Imprinting of Nerve Gases
    IMPORTANT INTERACTIONS IN PEPTIDE-BASED TRANSFECTION AGENTS, SUGARS AS CHIRAL SCAFFOLDS, AND MOLECULAR IMPRINTING OF NERVE GASES By FLORENT ALLAIS A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2004 Copyright 2004 by Florent Allais This is dedicated to my parents Nadine and Jacques. This is for Stanislas, especially, who inspires me daily. ACKNOWLEDGMENTS First and foremost I would like to thank my parents and my grandmother Maria. Their love, support, and understanding are a continuous source of strength. They have always continued to support me in whatever endeavor I choose and I will forever be grateful. I would also like to thank my great-grandmother Alberte, who taught me a lot while I was a child; and my grandfather Georges, whom I didn’t have the joy to really know. I am sure they would be really proud to see the individual I became and where I am now. There are other important persons in my life: Stanislas, the greatest man I could have ever found; my family (although some of them did or still behave in a way that disgusts and upsets me); Nathan, (though I haven’t known him for a long time, I know that we will be friends forever); and finally Xavier, who is someone I won’t forget, in spite of huge misunderstandings about life and relationships. Next I would like to thank Pr. Eric Enholm for being a great advisor, but more importantly an excellent teacher.
