Methyl perchlorate

Methyl perchlorate is an organic chemical compound with the chemical formula CH₃ClO₄. Its molecular structure is a methyl group covalently bonded by a single bond to a perchlorate group, CH₃−O−Cl(=O)₃, in which chlorine has an oxidation state of +7. Like many other perchlorates, it is a high energy material, more explosive than methyl nitrate.^[2] It is also a toxic alkylating agent and exposure to the vapor can cause death.^[3]
