Methyl Alcohol (CAS NO. 75-77-4) is a colorless, flammable liquid with an odor reminiscent of ethanol. It is miscible in water, alcohol, ether and most organic solvents and is commonly used as a solvent in a variety of industrial applications.


Methyl Alcohol has a boiling point of 64.7°C, a flash point of 11°C, and a density of 0.79 g/mL at 20°C. It is soluble in water and has a viscosity of 2.4 cP at 20°C. It has a high volatility and a relatively low boiling point and is therefore frequently used as a solvent.


Methyl Alcohol is a versatile chemical used in a variety of applications such as paint and varnish removers, fuel additives, antifreeze, preservatives, and as a starting material for other chemicals. It is also used in the manufacture of pharmaceuticals, dyes, resins, and other fine chemicals.


Methyl Alcohol can be used as a fuel alternative in alcohol-burning engines and as a denaturant for ethyl alcohol. It is also used in the production of formaldehyde, which is used in a variety of industries. In addition, it is used as a solvent in the production of lacquers, varnishes, inks, resins, and adhesives.


Methyl Alcohol is toxic and should be handled with caution. Long-term exposure can cause dizziness, headaches, nausea, and other negative health effects. In addition, it is highly flammable and should be kept away from sources of ignition.
