4-Dimethylaminoazobenzene
4-Dimethylaminoazobenzene, also known as butter yellow, is a lipophilic azo dye once used to color butter and margarine, best known as a potent liver carcinogen in experimental animals.
Alkene diazidation
Alkene diazidation is an organic reaction that adds two azide groups across an alkene's double bond, giving a vicinal diazide easily reduced to a 1,2-diamine.
Azide
An azide is a chemical species containing the three-nitrogen group N₃, a linear pseudohalide anion; sodium azide inflates airbags, while organic azides are versatile building blocks in click chemistry.
Diazomethane
Diazomethane (CH₂N₂) is the simplest diazo compound, a yellow gas that is highly toxic and explosive, so it is freshly prepared in dilute ether solution to methylate acids in the laboratory.
Hydrazoic acid
Hydrazoic acid, also called hydrogen azide or hydronitric acid, is the colorless, volatile, toxic and explosive liquid nitrogen hydride (HN₃) used to make heavy metal azides for shell detonators.
Trimethylsilyl azide
Trimethylsilyl azide (azidotrimethylsilane, TMS-N₃) is a moisture-sensitive, flammable liquid used in organic synthesis as an azide transfer reagent, making triazoles and tetrazoles, and as a safer substitute for hydrazoic acid.
