Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

4. Notwithstanding the provisions of this paragraph, the packing group and hazard zone of a tear gas substance is as assigned in Column 5 of the 49CFR 172.101 Table. The packing group and hazard zone for Division 6.1 mixtures that are poisonous (toxic) by inhalation may be determined by one of the following methods:
Some organochlorine compounds, such as sulfur mustards, nitrogen mustards, and Lewisite, are even used as chemical weapons due to their toxicity. However, the presence of chlorine in an organic compound does not ensure toxicity. Some organochlorides are considered safe enough for consumption in foods and medicines.
Methylene chloride is a prime example. The toxic chemical, often used to refinish furniture and bathtubs, has been linked to dozens of deaths since 1980. ... assistant administrator for the EPA ...
The handling of this chemical may incur notable safety precautions. ... log 10 of Dichloromethane vapor pressure. Uses formula: ...
For example, ethane with bromine becomes bromoethane, methane with four chlorine groups becomes tetrachloromethane. However, many of these compounds have already an established trivial name, which is endorsed by the IUPAC nomenclature, for example chloroform (trichloromethane) and methylene chloride (dichloromethane). But nowadays, IUPAC ...
The potential hazards of a chemical or a substitute candidate must be assessed by noting the toxicity of the chemical to both humans and the environment. An assessment of the chemical should list the dangerous properties of the chemical, such as flammability or corrosivity. [3]
Days after crews released and burned toxic chemicals transported by a wrecked train in Ohio, residents remain concerned about the toxic substances that could be lingering in their evacuated ...
