OEM Kina Kina GMP Factory Supply 2, 5-Dimethoxybenzaldehyde CAS 93-02-7 me ke kumu kūʻai nui
Manaʻo pinepine mākou e hoʻoholo ke ʻano o kekahi i ka maikaʻi o nā huahana, hoʻoholo nā kikoʻī i nā huahana 'maikaʻi loa, me ka ʻuhane limahana REALISTIC, EFFICIENT AND INOVATIVE no OEM China China GMP Factory Supply.2, 5-Dimethoxybenzaldehyde CAS 93-02-7me Wholesale Price, Ke kakali nei mākou i ka launa pū ʻana me nā mea kūʻai aku ma waho e pili ana i nā pono like. E ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku!
Manaʻo pinepine mākou e hoʻoholo ke ʻano o kekahi i ka maikaʻi o nā huahana, hoʻoholo nā kikoʻī i nā huahana 'maikaʻi loa, me ka ʻuhane limahana REALISTIC, EFFICIENT AND INOVATIVE no93-02-7 a me CAS 93-02-7, Ke hahai nei mākou i ka ʻoihana a me ka manaʻo o kā mākou hanauna kahiko, a makemake mākou e wehe i kahi manaʻo hou ma kēia kahua, Ke koi nei mākou i ka "Integrity, Profession, Win-win Cooperation", no ka mea, loaʻa iā mākou kahi kākoʻo ikaika, ʻo ia nā hoa maikaʻi me nā laina hana kiʻekiʻe, ka ikaika ʻenehana nui, ka ʻōnaehana nānā maʻamau a me ka mana hana maikaʻi.
ʻO 2,5-Dimethoxybenzaldehyde kahi pauka crystalline melemele māmā me ke kaumaha molekala o 166.18 a me kahi paila o 146°C. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol a me ka ether. Hoʻohana nui ʻia ia ma ke ʻano he pharmaceutical intermediate.

Ma waho aʻe o ka oxidized a i hoʻemi ʻia i2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl waiʻona, 2,5-dimethoxybenzaldehyde ponoʻī nō hoʻi ka waiwai hoʻohana kūikawā. Ma ka hana ʻana me nā mea me nā ʻano hui hana like ʻole, hiki ke loaʻa nā molekala lāʻau me nā ʻano like ʻole a me nā hopena like ʻole. ʻO ka maʻi o Parkinson (PD) he maʻi neurodegenerative maʻamau, a ʻo kāna mau hōʻailona koʻikoʻi e pili ana i ka haʻalulu ʻiʻo, ʻoʻoleʻa, paʻakikī o ka neʻe ʻana, ke kū ʻana o ke kino a me nā pilikia kaulike. ʻO ka hoʻomohala hou aʻe e alakaʻi i ka ʻike, ka ʻike, nā pilikia hoʻomanaʻo a me ka dementia maopopo. I kēia manawa, ʻo ka mālama ʻana i ka PD ka mea nui e pili ana i ka lāʻau lapaʻau, ka lāʻau lapaʻau a me ka lāʻau gene. I ka lāʻau lapaʻau, ua loaʻa ka phenamidine i ka hopena maikaʻi ma PD, me ka haʻahaʻa haʻahaʻa a me ka palekana maikaʻi, a ʻo ka synthesis o phenamidine e pono ai ka hoʻohana ʻana i ka 2,5-dimethoxybenzaldehyde i mea hoʻomaka.
Wahi a ke ʻano hana synthesis i hōʻike ʻia ma ka palapala, loaʻa ka 2,5-dimethoxybenzaldehyde ma ka hana ʻana i ka 1,4-dimethoxybenzene me kahi mea hana formylation. ʻO nā mea hana formylation ka (1) kahi hui o 1,1-dichloromethyl ether a me titanium tetrachloride; (2) kahi hui o N,N-dimethylformamide a me phosphorus oxychloride, kahi hui o N,N-dimethylformamide a me oxalyl chloride; (3) kahi hui o N,N-dimethylformamide a me thionyl chloride a i ʻole ka hui ʻana o ka urotropine a me ka magnesium chloride. Eia nō naʻe, pono kēia mau ʻano i ka hoʻohana ʻana i ka nui o ka titanium tetrachloride, phosphorus oxychloride a i ʻole thionyl chloride. ʻAʻole paʻa a maʻalahi kēia mau reagents, a ua hoʻokuʻu ʻia ka nui o ke kinoea hydrochloric acid i ka wā o ka hopena, ʻaʻole ia e pili i ke kaiapuni a loaʻa nā koi kiʻekiʻe no ke kaʻina hana.
Ua manaʻo ʻia kahi ala synthesis hou. Hoʻohana kēia ʻano hana i ka 1,4-dimethoxybenzene a me ka formaldehyde e like me nā mea maka, a hana i kahi hopena hoʻohui photooxidative i ke alo o ka oxygen a me ka catalyst ma lalo o ka irradiation kukui polū e hoʻohui pono i ka 2,5-dimethoxybenzaldehyde. Hoʻohana kēia ʻano i ka oxygen a i ʻole ka ea ma ke ʻano he oxidant, ʻaʻole e hoʻopuka i ke kinoea ʻakika, a pili i ke kaiapuni. Eia kekahi, hoʻohana kēia ʻano i ka cobalt cheap ma ke ʻano he catalyst, he haʻahaʻa i ke kumukūʻai a kūpono no ka noi ʻoihana.
