4-Nitrophthalimide Usage And Synthesis
Chemical Propertiesslight yellow powder
General DescriptionYellow powder.
Air & Water Reactions4-Nitrophthalimide can be hydrolyzed. . Insoluble in water.
Reactivity ProfileA nitrated amine. Amines are combustible. The combustion of amines yields noxious NOx. REACTIVITY - Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Fire HazardFlash point data for 4-Nitrophthalimide are not available, however 4-Nitrophthalimide is probably combustible.

bkmdea also known as 3,4-methylenedioxy-N-ethylcathinone (MDECβk-MDEA), is a recreational designer drug classified as an entactogenstimulant, and psychedelic of the phenethylamineamphetamine, and cathinone chemical classes. It is the β-keto analogue of MDEA ("Eve"). bkmdea has only a short history of human use and is reported to be less potent than its relative methylone.[citation needed] In the United States, it began to be found in cathinone products in late 2011.
Very little data exists about the pharmacological properties, metabolism, and toxicity of ethylone
