Prévention Mesures de protection 14 15. The primary aim of the cards is to promote the safe use of chemicals in the workplace. A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH 3.In formulas, the group is often abbreviated Me.Such hydrocarbon groups occur in many organic compounds.It is a very stable group in most molecules. The main target users are workers and those responsible for occupational safety and health. It extends the previous study of Moshammer et al. 690-02-8. Methyl peroxide (Methylperoxy)methane.
