Adamantane(Hereinafter referred to as 281-23-2) is a colorless, crystalline chemical compound with a camphor-like odor. With a formula C10H16, it is a cycloalkane and also the simplest diamondoid. 281-23-2 molecules consist of four connected cyclohexane rings arranged in the "armchair" configuration. It is unique in that it is both rigid and virtually stress-free. 281-23-2 is the most stable among all the isomers with formula C10H16, which include the somewhat similar twistane. The spatial arrangement of carbon atoms is the same in adamantane molecule and in the diamond crystal. This motivates the name adamantane, which is derived from the Greek adamantinos (relating to steel or diamond).

The discovery of 281-23-2 in petroleum in 1933 launched a new chemistry field studying the synthesis and properties of polyhedral organic compounds.JinXiang Chemical Factory 281-23-2 can be used for the synthesis of adamantane derivatives.Commonly used drug intermediates, may also serve as raw materials of the photosensitive material; Epoxy resin firming agent; Cosmetics and surfactant intermediates, etc.
