Ethyl nicotinate CAS 614-18-6
Ethyl nicotinate, hu ua ethyl pyridine-3-formate, yog ib qho ester derivative ntawm niacin (vitamin B3). Nws yog ib qho kua tsis muaj xim rau daj daj ntseg nrog me ntsis, tsw qab txiv hmab txiv ntoo sib txawv. Hauv kev lag luam thiab kev lag luam, ethyl nicotinate kuj hu ua ethyl paraben lossis ethyl nicotinate. Ethyl nicotinate tsis yaj hauv dej tab sis sib xyaw nrog cov organic solvents xws li ethanol, ether thiab chloroform.

1. Kev kho mob: Tsom ntsoov rau "kev noj vitamin ntxiv" thiab "kev kho mob hauv zos"
Raws li cov tshuaj nruab nrab lossis cov khoom siv tshuaj ncaj qha, qhov tseem ceeb ntawm ethyl niacin nyob rau hauv nws "kev ntxiv me me ntawm vitamin B3" thiab "kev cuam tshuam hauv zos".
2. Kev lag luam tshuaj txhua hnub: Tsom ntsoov rau "kev saib xyuas tawv nqaij" thiab "kev noj qab haus huv ntawm cov plaub hau"
Nrog nws cov "kev ua haujlwm me me + kev nkag tau zoo", ethyl niacin feem ntau siv rau hauv "cov qauv ua haujlwm" hauv kev saib xyuas tawv nqaij thiab cov khoom saib xyuas plaub hau:
3. Kev Noj Haus thiab Kev Pub Noj: "Kev Txhawb Nqa Khoom Noj" thiab "Kev Txhim Kho Qhov Qab"
Cov khoom noj khoom haus fortifier
Kev ntxiv vitamin B3 rau cov khoom ci (xws li mov ci thiab ncuav qab zib), dej haus kis las, thiab cov khoom noj ntxiv rau cov menyuam mos thiab cov menyuam yaus feem ntau muaj tus nqi ntxiv ntawm 0.01% txog 0.05% (raws li tag nrho cov khoom noj). Piv txwv li, kev ntxiv ethyl nicotinate rau cov khoom noj mov rau menyuam yaus tuaj yeem tiv thaiv qhov qaub ntawm niacin los ntawm kev cuam tshuam rau qhov saj, thaum ua tau raws li qhov xav tau ntawm cov menyuam mos rau vitamin B3 (qhov kev noj txhua hnub yog kwv yees li 4mg).
4. Lwm cov teb: Kev siv rau kev tshawb fawb txog kev lag luam thiab kev tshawb fawb
Cov tshuaj intermediates organic synthesis: Lawv siv rau hauv kev tsim cov pyridine derivatives (xws li cov tshuaj intermediates thiab dyes), thiab pawg ethyl ester tuaj yeem ua haujlwm ua "pab pawg tiv thaiv tshem tawm", qhia lwm pab pawg ua haujlwm los ntawm hydrolysis lossis txo cov tshuaj tiv thaiv.
Cov khoom xyaw pab txhawb kev tsw qab: Ntxiv me me (0.001% -0.005%) rau hauv cov tsw qab luam yeeb tuaj yeem txhim kho qhov saj mos mos ntawm luam yeeb thiab npog cov ntxhiab tsw phem.
Cov tshuaj reagent tshawb fawb: Siv rau hauv kev sim biochemical ua ib qho probe molecule rau "kev tshawb fawb txog kev hloov pauv ntawm niacin", ethyl nicotinate taug qab txoj kev hloov pauv ntawm niacin hauv cov hlwb.
1. Ethyl nicotinate tsis hnyav heev, tsis ua rau khaus thiab tsis ua rau tawv nqaij liab. Ethyl nicotinate zoo dua niacin thiab haum rau cov tawv nqaij rhiab heev, nrog rau cov khoom siv saib xyuas tawv nqaij rhiab heev thiab cov tshuaj vitamin noj.
2. Ethyl nicotinate muaj bioavailability siab thiab tuaj yeem nkag mus rau hauv daim tawv nqaij thiab cov ntaub so ntswg mucous. Tom qab hydrolyzed rau hauv niacin, nws muaj kev ua haujlwm siab thiab nws cov kev ua haujlwm zoo dua li ntawm niacin sab nraud ntshav-activating gel thiab kev saib xyuas plaub hau thiab cov khoom tiv thaiv plaub hau poob.
3. Ethyl nicotinate sib xws thiab yooj yim yaj hauv cov roj / dej, thiab tsis muaj kev sib cav nrog surfactants, preservatives, vitamins thiab lwm yam khoom xyaw. Ethyl nicotinate yog cov khoom siv saib xyuas tawv nqaij thiab cov mis tshuaj ntxiv rau zaub mov.
4. Ethyl nicotinate muaj kev nyab xeeb rau kev noj thiab siv rau sab nraud nrog kev lom tsawg thiab tau dhau daim ntawv pov thawj kev nyab xeeb hauv ntau lub tebchaws. Ethyl nicotinate yog qhov tsim nyog rau ntau tus neeg (cov menyuam mos thiab cov neeg laus), suav nrog cov khoom noj rau menyuam yaus thiab cov tshuaj.
