Chemical Properties
VERY SLIGHTLY BEIGE FLUFFY POWDER
Uses
3-Chloro-4-hydroxybenzoic acid serves as a precursor for the ambigol building block 2,4-dichlorophenol[1].
Synthesis
3-Chloro-4-hydroxybenzoic acid is produced starting from chorismate via 4-hydroxybenzoic acid, 4-hydroxybenzoyl-CoA, and 3-chloro-4-hydroxybenzoyl-SNAC through the action of Ab enzymes including the Ab9 release domains[1].
