O le dichloroacetic acid, e ta'ua fo'i o le dichloroacetic acid, o se vai e leai se lanu ma e manogi malosi. O lona mamafa molecular e 128.94, ma lona mafiafia e 1.5634. E lua foliga crystalline o le dichloroacetic acid ma le melting points e 9.7℃ ma le -4℃, i le faasologa. O lona boil point e 194℃, Chemicalbook 102℃ (2.666×10³ Pa), ma le 91–92℃ (1.600×10³ Pa). O lona refractive index e 1.4659. E mafai ona solo i le vai (8.63% i le 20℃), ethanol, methanol, diethyl ether, acetone, chloroform, ma le benzene.

O le dichloroacetic acid o se acid e sili atu lona malosi nai lo le chloroacetic acid, faatasi ai ma se dissociation constant K = 5 × 10⁻². O ona uiga fa'akemikolo e tutusa ma le chloroacetic acid. E mafai ona sui ia atomu chlorine e lua i totonu o le molecule dichloroacetic acid. E tali atu ma le phenol e fausia ai le diphenoxyacetic acid (Chemicaloacetic acid); ma le hydroxylamine e fausia ai le isonitroacetic acid, ma isi. E mafai foi ona faia ni tali esterification, e tali atu ma le ethanol e maua ai le ethyl dichloroacete. E mu ma e 'aina le dichloroacetic acid; o lona ausa e matua fa'aita ai le pa'u ma mata.

Fa'aaogāga: Fa'aaogāina o se vaila'au fa'asolosolo i vaila'au fa'asaina ma vaila'au.

Metotia Gaosiga: 1. Fa'a-Chlorination Acetic Acid Metotia Toe Fa'aleleia Mai le Acetic Acid: O le fa'a-chlorination o le acetic acid e maua ai le chloroacetic acid mother liquor. O lenei mother liquor e faia i le chlorination i lalo o le sulfur catalysis, sosoo ai ma le fa'amamāina e maua ai le dichloroacetic acid. 2. Metotia Trichloroacetaldehyde: E maua le Trichloroacetaldehyde e ala i le cyanidation, dehydrochlorination, ma le hydrolysis. 3. Metotia Acetic Acid: E maua le acetic acid e ala i le chlorination i lalo o le iodine catalysis.
