Methanol is a core feedstock in the production of formaldehyde, acetic acid, and methyl tert-butyl ether (MTBE), all of which feed into plastics, resins, and fuel additive manufacturing. It also functions as a general solvent across chemical processing operations where its fast evaporation and miscibility are assets. Its role as an antifreeze component rounds out its industrial footprint, particularly in applications where low-temperature fluidity is required.

In the lab, methanol is a standard mobile phase solvent for HPLC and other chromatography methods, valued for its purity and consistent elution behavior. It also serves as a general reagent in organic synthesis and as a base solvent in NMR sample preparation. Its availability in high-purity grades makes it a dependable choice when analytical precision is non-negotiable.

Methanol acts as the primary transesterification agent in biodiesel production, converting fats and oils into fatty acid methyl esters. It is also used as a denaturant added to ethanol to render it unfit for consumption in industrial formulations, and as a component in windshield washer fluid and certain fuel additives. These specialized uses depend on methanol's reactivity and low cost relative to alternative alcohols.

Methanol carries a GHS signal word of Danger and is classified as both a flammable liquid and an acute toxicant through oral, dermal, and inhalation exposure. Repeated or prolonged exposure has been linked to optic nerve damage and vision loss, making exposure control a priority rather than an afterthought. Handlers should treat any methanol exposure, however minor it seems, as a reason to stop and assess rather than continue working.

Chemical-resistant gloves made of nitrile or butyl rubber are required when handling methanol directly, along with safety goggles or a face shield to protect against splash exposure. In areas with limited ventilation, a NIOSH-approved organic vapor respirator should be worn to limit inhalation exposure. PPE selection should match the scale and duration of the task, with higher-protection equipment used for bulk transfers or extended handling.

Methanol should be stored in a cool, well-ventilated area away from heat, sparks, and open flame, with containers kept tightly sealed at all times. Grounded and bonded containers are necessary to prevent static discharge during transfer, given the liquid's low flash point. Storage areas must also be separated from strong oxidizers and acids to eliminate the risk of dangerous reactions.

In the event of a spill, all ignition sources should be eliminated immediately and the area ventilated before cleanup begins. Spills should be absorbed using inert material such as sand or vermiculite rather than washed down drains or into waterways. Disposal must follow federal, state, and local hazardous waste regulations, since methanol does not qualify for standard liquid waste disposal.
