I-Methyl (R)-(-)-3-hydroxybutyrate (CAS#3976-69-0) Isingeniso

I-Methyl (R) -3-hydroxybutyrate(Methyl (R) -3-hydroxybutyrate) iyinhlanganisela yezinto eziphilayo. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:

Imvelo:
I-Methyl (R) -3-hydroxybutyrate iwuketshezi olungenambala olunephunga elikhethekile. Ifomula yayo yamakhemikhali ithi C5H10O3 futhi isisindo sayo samangqamuzana esihlobene singu-118.13g/mol. Iyakwazi ukuvutha futhi ingancibilika kuzincibilikisi eziningi eziphilayo.

Sebenzisa:
I-Methyl (R) -3-hydroxybutyrate isetshenziswa kakhulu ekuhlanganiseni izinhlanganisela eziphilayo njengezibulala-zinambuzane, imithi nezinongo. Ingasetshenziselwa ukuhlanganiswa kwezidakamizwa ezintsha ezilwa namagciwane kanye ne-antitumor emkhakheni wezokwenziwa kwemithi, futhi iphinde isetshenziswe njengendawo ephakathi kokwenziwa kwe-organic synthetic.

Indlela Yokulungiselela:
Ngokuvamile, indlela yokulungiselela i-Methyl (R) -3-hydroxybutyrate itholakala nge-methyl esterification ye (R) -3-oxobutyric acid. Izinyathelo ezithile zifaka ukusabela (R) -3-oxobutyric acid nge-methanol, nokwenza ukusabela kwe-esterification ngaphansi kwe-acid catalysis ukuze kutholwe umkhiqizo.

Ulwazi Lokuphepha:
I-Methyl (R) -3-hydroxybutyrate idinga ukuphepha ngesikhathi sokugcina nokusebenza. Kuyinto evuthayo futhi kufanele igwenywe ukuthintana namalangabi avulekile noma amazinga okushisa aphezulu. Gwema ukuhogela umhwamuko noma ukuthintana nesikhumba namehlo ngesikhathi sokuwusebenzisa. Uma kwenzeka uthintana ngephutha, geza ngamanzi ngokushesha futhi ufune usizo lwezokwelapha. Ngesikhathi esifanayo, kufanele isetshenziswe endaweni engenawo umoya futhi ifakwe izinto zokuzivikela ezifanele, njengezibuko zamakhemikhali namagilavu.
