Sublimed chloroacetic acid crystals in a 50 year old bottle.

Chloroacetic acid a quite often used chemical, it is produced in several thousand metric tons (over 706,000 tonnes/year) and it has a LOT application in chemistry.

Chloroacetic acid or monochloroacetic acid is a crystalline compound, highly hygroscopic and it’s a bit stronger acid compared to acetic acid. It is usually shipped in glass or plastic bottles and it’s dirt cheap, usually the container cost more than the acid in it and the shipping costs MUCH more than the chemical what was transported.

It’s important to note that like other chloroacetic acids and related halocarbons, chloroacetic acid is a hazardous alkylating agent. The LD50 for rats is 76 mg/kg. Chloroacetic acid easily penetrates skin and mucous membranes and interferes with cellular energy production. Initial dermal exposure to high concentrations (e.g., 80% solution) may not appear very damaging at first, however systemic poisoning may present within hours.
