Pharmaceutical intermediates xa mus rau qee cov khoom siv tshuaj lom neeg lossis cov khoom siv tshuaj siv hauv cov txheej txheem tshuaj synthesis.
Raws li kev lag luam, kev lag luam tshuaj intermediates, ua ib qho tseem ceeb ntawm kev lag luam tshuaj zoo, yuav muaj qhov chaw loj hlob nyob rau yav tom ntej.

Los ntawm txoj kev loj hlob keeb kwm ntawm Tuam Tshoj tus kws tshuaj intermediates kev lag luam, tom qab ze li ntawm 30 xyoo ntawm txoj kev loj hlob, kws tshuaj intermediates tau tsim los ntawm ib tug me me ceg ntawm tshuaj lom neeg kev lag luam mus rau hauv ib tug tshiab kev lag luam nrog ib tug tsim nyog tus nqi ntawm billions ntawm yuan, thiab kev ua lag luam kev sib tw yog nce zuj zus. .
Nws yog to taub hais tias nyob rau hauv lub thaum ntxov theem ntawm kev loj hlob ntawm cov tshuaj intermediates kev lag luam, vim me me peev thiab siab tus nqi rov qab, kws intermediates tuam txhab uas muag zoo li xyoob tua tom qab ib tug los nag, tshwj xeeb tshaj yog nyob rau hauv Zhejiang, Taizhou, Nanjing thiab lwm qhov chaw uas muaj dej siab. tej yam kev mob rau kev loj hlob ntawm cov tshuaj intermediates kev loj hlob yog tshwj xeeb yog ceev.
Tam sim no, raws li kev hloov pauv ntawm cov qauv kev lag luam kho mob, nrog rau kev tsim cov tshuaj tshiab ntawm kev ua lag luam raug txwv, qhov nyuaj ntawm kev lag luam tshuaj intermediates kev lag luam tshiab cov khoom lag luam loj hlob ntau dua, cov khoom lag luam ib txwm muaj kev sib tw hnyav dua. , kws tshuaj intermediates kev lag luam profits poob sai heev, thiab kws tshuaj intermediates ua ib tug yuav tsum xav txog qhov teeb meem ntawm yuav ua li cas txoj kev loj hlob ntawm ib tug enterprise.
Kev lag luam ntseeg tias nws tuaj yeem tsim tau nws tus kheej qhov zoo ntawm kev sib tw los ntawm kev siv thev naus laus zis, kev cuam tshuam, kev hloov pauv thiab lwm yam, kom sawv tawm hauv kev ua lag luam.
Hais txog kev siv tshuab, nws tsuas yog hais txog kev txhim kho thev naus laus zis thiab txuag nqi.
Nws tau tshaj tawm tias cov tshuaj intermediates muaj cov txheej txheem ntev, ntau cov kauj ruam cov tshuaj tiv thaiv, cov kuab tshuaj loj, thiab muaj peev xwm zoo rau kev txhim kho.
Piv txwv li, cov khoom siv qis qis tuaj yeem siv los hloov cov ntaub ntawv muaj txiaj ntsig ntau dua, xws li hloov bromine hauv kev tsim cov aminotaxime acid, ammonium thiocyanate es tsis txhob siv cov poov tshuaj thiocyanate (sodium) hauv kev tsim khoom, thiab lwm yam.
Tsis tas li ntawd, ib qho hnyav hnyav kuj tuaj yeem siv los hloov cov kuab tshuaj sib txawv hauv cov txheej txheem tshuaj tiv thaiv, thiab cov cawv uas tsim los ntawm hydrolysis ntawm ester cov khoom tuaj yeem rov qab tau.
Nyob rau hauv lub nam ntawm lub hwj chim, nws yog tsuas yog los tsim nws tus kheej yam ntxwv cov khoom thiab txhim kho lub hwj chim nyob rau hauv kev lag luam.
Nws yog to taub hais tias vim hais tias ntawm Tuam Tshoj tus kws tshuaj intermediates kev lag luam, cov khoom homogenization kev sib tw yog loj, yog hais tias lub tuam txhab muaj peev xwm tsim lawv tus kheej superior khoom, yuav muaj peev xwm tuav tau ntau yam zoo nyob rau hauv lub lag luam.
Nyob rau hauv cov nqe lus ntawm transformation, tam sim no, nrog rau cov domestic ib puag ncig tiv thaiv yuav tsum nruj me ntsis, cov kev pab cuam yog inclined mus rau siab nqi-ntxiv industries, thiab nrog rau kev nce ntawm ib puag ncig tiv thaiv tus nqi, transformation tau dhau los ua ib qho teeb meem uas kws tshuaj intermediates tuam txhab uas muag yuav tsum tau xav txog. kev tsim kho kom ruaj khov.
Nws tau pom zoo tias cov chaw lag luam tshuaj intermediates txuas ntxiv cov kev lag luam txuas mus rau sab saud thiab qis qis, thiab hloov cov ntaub ntawv tseem ceeb uas lawv siv rau lawv tus kheej ntau lawm, uas tuaj yeem txo tus nqi ntxiv. Lub caij no, rau qee cov khoom siv raw tshwj xeeb, nws tuaj yeem zam kev monopoly ntawm cov ntaub ntawv tseem ceeb.
Kev lag luam hais tias kev txav mus los ntawm txoj kev, qhov chaw kws tshuaj intermediates ncaj qha koom nrog APIs, tuaj yeem ua rau muaj txiaj ntsig ntxiv ntawm cov khoom thaum muag ncaj qha rau cov tuam txhab tshuaj.
Nws yog ib qho tsim nyog yuav tsum nco ntsoov tias kev nqis peev qis qis yog qhov loj dua, thaum cov khoom siv thev naus laus zis siab dua, thiab nws yuav tsum muaj kev sib raug zoo nrog cov tuam txhab uas siv API.
Ntawm qhov tod tes, cov tuam txhab ua lag luam yuav tau txais txiaj ntsig kev sib tw ntau dua.
Tsis tas li ntawd, kev tshawb fawb thiab kev loj hlob yog qhov tseem ceeb heev rau kev lag luam nruab nrab. Tam sim no, kev lag luam tshuaj nruab nrab hauv Suav teb feem ntau them me ntsis rau kev tshawb fawb thiab kev loj hlob.
Yog li ntawd, nyob rau hauv ib puag ncig ntawm kev txhim kho cov kev xav tau tas li, kev lag luam R & D muaj zog nrog R & D lub zog yuav los ua ntej, thaum cov lag luam me thiab nruab nrab tsis muaj peev xwm R & D yuav raug tshem tawm los ntawm kev ua lag luam. Nyob rau hauv lub neej yav tom ntej, kev lag luam concentration yuav nce ntxiv, thiab theem nrab thiab qis kawg kev loj hlob yuav loj hlob mus rau theem siab dua.
