Clear yellow Liquid??
LDAO is suitable to use in crystallization of membrane proteins. It is also suitable to enhance the detection of high molecular weight proteins.?? ??
Lauryldimethylamine oxide(LDAO) is mainly used in cosmetic and personal care product formulations, particularly in hair care products as a foaming agent, fragrance ingredient, viscosity builder, stabiliser, conditioner, emulsifier, wetting agent and antistatic agent. It is also a biochemical reagent and can be used as a biological material or organic compound for life science related research.?? ??
Crystalline solid.??? ?? ??
Hygroscopic .?? ???
LDAO is less basic than the tertiary amine from which LDAO is derived, but still reacts with strong acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.????
Flash point data for LDAO are not available. LDAO is probably nonflammable.Purification Methods
Crystallise the oxide from acetone or ethyl acetate. [Bunton et al. J Org Chem 52 3832 1987, Beilstein 4 III 410, 4 IV 798.]N,N-????????? N-??? ?? ?? ? ???
