Product Information

• Name: 4-(2-Hydroxyethoxycarbonyl)benzoate
• Brand: Biosynth
• Description: 4-(2-Hydroxyethoxycarbonyl)benzoate (4HB) is a monomer of poly(4HB). It is used as a biodegradable polymer for the synthesis of hydrogels. 4HB is synthesized from the corresponding dicarboxylic acid, which contains two or more carboxyl groups. The synthesis of 4HB involves esterification with 2-hydroxyethanol and subsequent alkali hydrolysis to remove water. The product is purified by precipitation with ethanol, filtration, and vacuum drying. 4HB has been used as a substrate in biological treatment processes such as anaerobic digestion and aerobic composting. 4HB can be used as a functional group that can react at various temperatures, making it suitable for thermophilic organisms like Thermus aquaticus. The phylogenetic tree of the enzyme β-galactosidase reveals that the enzyme evolved from a common ancestor shared with LacB (β-
