Bromomethane, commonly known as methyl bromide, is an organobromine compound with formula C H 3 Br. This colorless, odorless, nonflammable gas is produced both industrially and biologically. This colorless, odorless, nonflammable gas is produced both industrially and biologically.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
The most pervasive is the naturally produced bromomethane. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants , and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.
The substance may be hazardous to the environment, and special attention should be given to aquatic organisms. Its volatility and environmental persistence makes bromoform's release, either as liquid or vapor, strongly inadvisable. Bromoform can be absorbed into the body by inhalation and through the skin.
The monohalomethanes are organic compounds in which a hydrogen atom in methane is replaced by a halogen.They belong to the haloalkanes or to the subgroup of halomethanes.. The four common [a] members are fluoromethane, chloromethane, bromomethane and iodomethane.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Feb. 3—SANTA FE — The U.S. Environmental Protection Agency on Thursday announced two proposed rules "to ensure that certain per- and polyfluoroalkyl substances (PFAS), also known as 'forever ...
Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages.
