Ethyl nicotinate CAS 614-18-6
Ethyl nicotinate, e tsejoang ka lik'hemik'hale e le ethyl pyridine-3-formate, ke ester derivative ea niacin (vithamine B3). Ke mokelikeli o se nang 'mala ho isa ho o mosehla o bobebe o bonaletsang o nang le monko o bobebe, o ikhethang oa litholoana. Masimong a khoebo le a indasteri, ethyl nicotinate e boetse e tsejoa e le ethyl paraben kapa ethyl nicotinate. Ethyl nicotinate ha e qhibilihe metsing empa e ka kopanngoa le metsoako ea lintho tse phelang e kang ethanol, ether le chloroform.

1. Lefapha la bongaka: Tsepamisa maikutlo ho "tlatsetso ea livithamine" le "kalafo ea lehae"
Jwalo ka karolo ya meriana e bohareng kapa e tobileng, boleng ba mantlha ba ethyl niacin bo ho "tlatsetso e bonolo ya vithamine B3" le "phello ya ho shebana le sebaka".
2. Indasteri ea lik'hemik'hale ea letsatsi le letsatsi: Ho tsepamisa maikutlo ho "tlhokomelo ea letlalo" le "bophelo bo botle ba moriri"
Ka "mosebetsi oa eona o bobebe + ho kenella hantle ha metsi", ethyl niacin hangata e sebelisoa "mekhoeng e sebetsang" lihlahisoa tsa tlhokomelo ea letlalo le tlhokomelo ea moriri:
3. Masimo a Lijo le Fepa: "Matlafatso ea Phepo" le "Ntlafatso ea Tatso"
Se matlafatsang limatlafatsi tsa lijo
Matlafatso ea vithamine B3 bakeng sa lintho tse besitsoeng (tse kang bohobe le libiskiti), lino tsa lipapali, le lijo tse tlatsetsang bakeng sa masea le bana ba banyenyane hangata li na le sekhahla sa ho eketsa sa 0.01% ho isa ho 0.05% (ho latela bongata ba lijo). Mohlala, ho eketsa ethyl nicotinate lijong-thollo tsa raese tsa masea ho ka thibela bolila ba niacin ho ama tatso, ha ka nako e ts'oanang ho fihlela tlhoko ea lesea ea vithamine B3 (tekanyo e khothaletsoang ea letsatsi le letsatsi ke hoo e ka bang 4mg).
4. Makala a mang: Ditshebediso tsa dipatlisiso tsa indasteri le tsa saense
Di-intermediate tsa tlhahiso ya tlhaho: Di sebediswa tlhahisong ya di-derivatives tsa pyridine (tse kang di-intermediate tsa meriana le didae), mme sehlopha sa ethyl ester se ka sebetsa e le "sehlopha se sireletsang se ka tloswang", se hlahisang dihlopha tse ding tse sebetsang ka hydrolysis kapa dikarabelo tsa phokotso.
Dikarolo tse thusang tsa tatso: Tekanyo e nyane (0.001%-0.005%) e ekelitsoeng tatsong ea koae e ka ntlafatsa tatso e bonolo ea koae le ho pata menko e bohale.
Reagent ea lipatlisiso: E sebelisoa litekong tsa biochemical e le molek'hule ea probe bakeng sa "lipatlisiso tsa metabolism ea niacin", ethyl nicotinate e latela tsela ea phetoho ea niacin ka har'a lisele.
1. Ethyl nicotinate e bobebe, ha e halefise haholo mme e na le kotsi e tlase ya ho hlatsuwa. Ethyl nicotinate e feta niacin mme e loketse letlalo le bonolo, hammoho le dihlahiswa tsa tlhokomelo ya letlalo le bonolo le di-supplement tsa divithamine tse nowang.
2. Ethyl nicotinate e na le bioavailability e phahameng 'me e ka kenella habonolo letlalong le lera la mucous. Kamora ho hasoa ka hydrolyzed ho ba niacin, e na le ts'ebetso e phahameng 'me ts'ebetso ea eona e phahametse ea niacin ea kantle e kenyang mali le lihlahisoa tsa tlhokomelo ea moriri le tse thibelang tahlehelo ea moriri.
3. Ethyl nicotinate e tsamaellana le yona mme e qhibiliha habonolo ditsamaisong tsa oli/metsi, mme ha e na kgohlano le di-surfactants, di-preservative, divithamine le metswako e meng. Ethyl nicotinate ke sehlahiswa sa tlhokomelo ya letlalo se kopaneng le foromo ya ho matlafatsa dijo.
4. Ethyl nicotinate e bolokehile bakeng sa tšebeliso ea molomo le ea letlalo e nang le chefo e tlase 'me e fetile mangolo a polokeho linaheng tse ngata. Ethyl nicotinate e loketse batho ba bangata (masea le batho ba hōlileng), ho kenyeletsoa lijo tsa masea le litokisetso tsa meriana.
