Okumaphakathi kokwenziwa kwe-allopurinol.

Ingenye ye-3-amino-4-substituted pyrazole series.Ingasetshenziswa njengendawo ephakathi ukuze ihlanganise izinhlanganisela eziningi ze-organic ezisebenza kahle ngokwemithi, njenge-allopurinol, enye yochungechunge lwe-pyrazolopyrimidine derivatives, yakamuva kusukela ngo-1963 Kusukela ekusetshenzisweni kwayo emtholampilo, ibiwumuthi oyinhloko wokwelapha i-gout.Njengamanje, zimbalwa izindlela ezaziwayo zokuhlanganisa

I-3-aminopyrazole-4-carboxamide hemisulfate e-China, ikakhulukazi ngokusabela i-malononitrile ne-triethyl orthoformate ukuze kulungiswe i-ethoxymethylene malononitrile, bese kuthi Ukusabela kwe-hydrazine hydrate kukhiqiza i-3-amino-4-cyanopyrazole, ekugcineni isabela nge-asidi egxilile ukukhiqiza i-sulfuric acid.

I-3-aminopyrazole-4-carboxamide hemisulfate (Chen Huiru, Xiao Guomin et al. 3-aminopyrazole- Synthesis of 4-formamide hemisulfate [J]. Chemical Industry Times, 2008, 6 (22): 39 40), isamba sesivuno ukuhlanganiswa ngale ndlela cishe ku-60% (kubalwa njenge-malononitrile), le ndlela ihilela ukusabela kwezinyathelo ezintathu, izinyathelo zide, futhi ama-reagents asetshenzisiwe, njenge-malononitrile ne-ethoxymethylene malononitrile, anobuthi kakhulu futhi ayabiza.Ngaphezu kwalokho, i-3-aminopyrazole-4 elungiselelwe ngale ndlela -Formamide hemisulfate inombala onzima ukuwususa futhi udinga ukucubungula okwengeziwe, okuyinkimbinkimbi kakhulu.

Kukhona imibiko ezincwadini zakwamanye amazwe kusetshenziswa i-pyridylamide hydrazone kanye ne-ethoxymethylene malononitrile njengezinto zokusetshenziswa ukuze kutholwe i-3-amino-4-cyanopyrazole ngokuhlanganisa kanye ne-cyclization, bese kusabela nge-sulfuric acid egxilile ukuze kutholwe inhlanganisela ehlosiwe (Reuken G Jones. Ukusabela kwama-orthoesters nge i-activemethylene compounds[J]. J Am Chem Soc. 1952,74(5) :4889 4891).Izinto zokusetshenziswa eziyinhloko ezisetshenziswa kule ndlela ziyabiza, isivuno sokusabela asiphezulu, futhi inzuzo yokukhiqizwa kwezimboni iphansi.Kumele kube nzima.

Sizinikezele ekulawuleni okuhle kakhulu kanye nenkampani yabathengi ecabangelayo, abasebenzi bethu abanokuhlangenwe nakho esisebenzisana nabo bavame ukutholakala ukuze baxoxe ngezimfuno zakho futhi benze okuthile okugcwele komthengi kujabulele Ukunikezwa kwencazelo ephezulu 99% Imidazole/1h-Imidazole/Imz CAS 288-32-4, We' usulungele ukubambisana nabangane abahle bebhizinisi abavela endlini yakho naphesheya kwezilwandle futhi nenze isikhathi eside esihle kakhulu ngokuhlangene.
Ukuchazwa okuphezuluChina Imidazole and Imz, Unyaka ngamunye, amakhasimende ethu amaningi ayevakashela inkampani yethu futhi azuze intuthuko enkulu yebhizinisi esebenza nathi.Sikwamukela ngobuqotho ukuthi usivakashele nganoma yisiphi isikhathi futhi ngokubambisana sizophumelela ekuphumeleleni okukhulu embonini yezinwele.
