| FDA-Anforderungen | The Food and Drug Administration has determined that gentian violet is not generally recognized as safe for use in animal feed and is a food additive subject to section 409 of the Federal Food, Drug, and Cosmetic Act (the act), unless it is intended for use as a new animal drug, in which case it is subject to section 512 of the act. The Food and Drug Administration has determined that gentian violet is not prior sanctioned for any use in animal feed.The Food and Drug Administration (FDA) has determined that gentian violet is not generally recognized as safe and effective for any veterinary drug use in food animals and is a new animal drug subject to section 512 of the Federal Food, Drug, and Cosmetic Act. FDA has determined that gentian violet is not exempted from new animal drug status under the "grandfather" provisions of the Drug Amendments of 1962 (21 U.S.C. 342).The Food and Drug Administration has determined that gentian violet has not been shown by adequate scientific data to be safe for use in animal feed. Use of gentian violet in animal feed causes the feed to be adulterated and in violation of the Federal Food, Drug, and Cosmetic Act (the act), in the absence of a regulation providing for its safe use as a food additive under section 409 of the act, unless it is subject to an effective notice of claimed investigational exemption for a food additive under section 570.17 of this chapter, or unless the substance is intended for use as a new animal drug and is subject to an approved application under section 512 of the act, or an index listing under section 572 of the act, or an effective notice of claimed investigational exemption for a new animal drug under part 511 of this chapter or section 516.125 of this chapter. |
Anwendungen & Verwendung
Beschreibung
Crystal Violet is light sensitive. May react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen.
Occurrence
Gentian is a fl owering perennial found in Europe and Asia.
Verwenden
Crystal Violet is used as an acid-base indicator, an alcohol denaturant, a biological stain, a textile dye and an indicator for copper salts. It is a component of gram staining in microorganisms and cell lines.
Herstellung & Synthese
synthetische
It is manufactured through using N, N-dimethylaniline as raw materials, followed by condensation, addition, chlorination and other reactions. Alternatively, it can be synthesized through the reaction between Michler ketone and N, N-dimethylaniline reaction in the presence of phosphorus oxychloride, followed by azeotropic reaction with hydrochloric acid. Recrystallization in hot water will generate compound containing nine crystal water molecules.
