Muaj nuj nqi thiab kev siv:

Estradiol benzoate hmoov 50-50-0yog ib qho hluavtaws estrogen compound nrog cov haujlwm hauv qab no thiab kev siv:

• Kev Kho Mob Menopausal Syndrome: Vim tias qhov txo qis hauv cov tshuaj estrogen hauv cov poj niam cev xeeb tub, tuaj yeem muaj cov tsos mob xws li txo cov pob txha ceev thiab muaj kev pheej hmoo ntawm cov kab mob plawv. Benzyl estradiol tuaj yeem hloov cov tshuaj estrogen thiab txo cov tsos mob ntawm menopausal.
• Kev tiv thaiv kab mob osteoporosis: Estrogen yog ib qho tseem ceeb regulator ntawm calcium nqus nyob rau hauv cov pob txha, thiab ib tug deficiency ntawm estrogen yuav ua rau osteoporosis. Benzyl estradiol, raws li cov tshuaj estrogen, pab tswj cov calcium tshuav thiab tiv thaiv pob txha.
• Kev txhawb nqa kev noj qab haus huv ntawm lub cev: Estrogen ua lub luag haujlwm tseem ceeb hauv cov poj niam kev ua me nyuam los ntawm kev txhawb nqa kev loj hlob ntawm zes qe menyuam, follicle maturation, thiab tswj kev loj hlob zoo thiab tso tawm ntawm uterine endometrium. Benzyl estradiol, raws li cov tshuaj estrogen, tuaj yeem hloov cov tshuaj estrogen tsis txaus hauv lub cev thiab txhawb kev noj qab haus huv ntawm cov menyuam yaus.

Cov txheej txheem xeem:

Cov ntsiab lus:Cov khoom no yog {{0}}hydroxyestra-1,3,5(10)-trien-17 -ol-3-benzoate, xam rau qhuav hauv paus , nrog rau cov ntsiab lus ntawm C25H28O3 xws li 97.0% mus rau 103.0%.

Qhov tsos:Cov khoom no yog cov hmoov dawb crystalline tsis muaj ntxhiab tsw.

Solubility:Me ntsis soluble nyob rau hauv acetone, me ntsis soluble nyob rau hauv ethanol los yog zaub roj, insoluble nyob rau hauv dej.

Melting Point:Lub melting point ntawm cov khoom no (raws li txoj cai 0612) yog 191-196 degree .

Kev sib hloov tshwj xeeb:Siv cov khoom tsim nyog ntawm cov khoom no, ntsuas kom raug, yaj nws hauv dioxane, thiab dilute nws mus rau cov tshuaj uas muaj 10mg ib 1mL. Ntsuas qhov kev sib hloov tshwj xeeb raws li cov cai (txoj cai 0621), uas yuav tsum nyob nruab nrab ntawm +58 degree thiab +63 degree .

Absorption Coefficient:Siv cov khoom tsim nyog ntawm cov khoom no, ntsuas kom raug, yaj nws hauv anhydrous ethanol, thiab dilute nws mus rau cov tshuaj uas muaj 10µg ib 1mL.
