White or slightly beige agglomerating crystals | [Uses]
Ethanolamine hydrochloride has been used:
- in overnight incubation of the tips to attach primary amine groups at the tip surface
- in the preparation of DMEM (dulbecco′s modified eagle′s medium)/F-12 media to culture human epidermal growth factor receptor 2 (HER2) cells derived from MMTV-HER2 transgenic mouse mammary tumors
- to administer the cultures to study its effect on the endogenous phosphatidyl ethanolamine pool and autophagy process
| [Biochem/physiol Actions]
Ethanolamine hydrochloride is utilized as a carbon and nitrogen source by bacteria that differs phylogenetically. It exists as phosphotidylethanolamine in the bacterial and mammalian cell membrane. Ethanolamine-ammonia lyase is responsible for the degradation of ethanolamine into acetaldehyde and ammonia. Ethanolamine is known to positively support lipid accumulation in photosynthetic organism model. | [Synthesis]
General procedure for the synthesis of ethanolamine hydrochloride from 2-aminoethanol:
Reagents and reaction conditions: 36% concentrated hydrochloric acid, room temperature.
Operating steps:
1. 15.0 g of 2-aminoethanol was weighed and added to three reaction flasks.
2. 27.0 g of 36% concentrated hydrochloric acid was added dropwise at a constant rate through a dropping funnel under stirring conditions, and the reaction temperature was controlled to be no more than 40 °C. 3.
3. after completion of the dropwise addition, the reaction mixture was continued to be stirred for 20 minutes until the pH was about 2 and the reaction was terminated.
4. remove water from the reaction system by concentration under reduced pressure until a very small amount of water remains.
5. A small amount of toluene was added and the residual water was further removed by azeotropic distillation.
6. The reaction mixture was rapidly cooled to give 23.7 g of a slightly light brown solid product, ethanolamine hydrochloride (M-07), in 99% yield. | [Purification Methods]
Recrystallise the salt from EtOH. It is deliquescent; store it dry. [Beilstein 4 IV 1406.] | [References]
