3-Mercaptopropionic acid (3-MPA) is an organosulfur compound with the formula HSCH 2 CH 2 CO 2 H. It is a bifunctional molecule, containing both carboxylic acid and thiol groups. It is a colorless oil.
Ethyl propionate is an organic compound with formula C 2 H 5 O 2 CCH 2 CH 3. It is the ethyl ester of propionic acid. It is a colorless volatile liquid with a pineapple-like odor. [3] Some fruits such as kiwis [4] and strawberries [5] contain ethyl propionate in small amounts.
Solubility in water decreases rapidly with increasing molar mass. Secondary hydroxyl groups in PPG are less reactive than primary hydroxyl groups in polyethylene glycol. PPG is less toxic than PEG, so biotechnologicals are now mainly produced with PPG. [4] [5] [6] Difference in water solubility of PPG4000 and PPG400
Pentaerythritol was first reported in 1891 by German chemist Bernhard Tollens and his student P. Wigand. [5] It may be prepared via a base-catalyzed multiple-addition reaction between acetaldehyde and 3 equivalents of formaldehyde to give pentaerythrose (CAS: 3818-32-4), followed by a Cannizzaro reaction with a fourth equivalent of formaldehyde to give the final product plus formate ion.
