4-Aminobenzoic acid (also known as para-aminobenzoic acid or PABA because the two functional groups are attached to the benzene ring across from one another in the para position) is an organic compound with the formula H 2 NC 6 H 4 CO 2 H. PABA is a white crystalline solid, [3] although commercial samples can appear gray. It is slightly soluble ...
Padimate O is an organic compound related to the water-soluble compound PABA (4-aminobenzoic acid) that is used as an ingredient in some sunscreens. This yellowish water-insoluble oily liquid is an ester formed by the condensation of 2-ethylhexanol with dimethylaminobenzoic acid. Other names for padimate O include 2-ethylhexyl 4 ...

Diethylethanolamine is used as a corrosion inhibitor in steam and condensate lines by neutralizing carbonic acid and scavenging oxygen. Diethylethanolamine reacts with 4-aminobenzoic acid to make procaine. DEAE is a precursor for DEAE-cellulose resin, which is commonly used in ion exchange chromatography.
It also can be prepared by treating benzaldehyde under nitration conditions, a process that initially converts the aldehyde to the acid. 4-Nitrobenzoic acid is a precursor to 4-aminobenzoic acid, which is in turn used to prepare the anesthetic procaine. 4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene.
It is the ester of 4-aminobenzoic acid and butanol. [1] A white, odourless, crystalline powder. that is mildly soluble in water (1 part in 7000) and soluble in alcohol, ether, chloroform, fixed oils, and dilute acids. It slowly hydrolyses when boiled with water. Synonyms include Butamben, Butilaminobenzoato, and Butoforme.
