Nā Huahana Hana Pono 2, 5-Dimethoxybenzaldehyde CAS 93-02-7
Ua paʻa mākou i ka hāʻawi ʻana i ka lawelawe kūʻai kūʻai maʻalahi, mālama manawa a mālama kālā no ka Personlized Products 2, 5-Dimethoxybenzaldehyde CAS 93-02-7.
Ua paʻa mākou i ka hāʻawi ʻana i ka lawelawe kūʻai kūʻai maʻalahi, mālama manawa a mālama kālā hoʻokahi no ka mea kūʻai aku.93-02-7 a me 2 5-Dimethoxybenzaldehyde, Ke hahai nei mākou i nā hana ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i kēia mau huahana e hōʻoia i ka lōʻihi a me ka hilinaʻi o nā huahana. Ke hahai nei mākou i nā kaʻina holoi holoi maikaʻi hou loa a hiki iā mākou ke hāʻawi i ka maikaʻi ʻole o nā huahana no kā mākou mea kūʻai. Hoʻoikaika mau mākou no ka hemolele a ke kuhikuhi ʻia kā mākou mau hana āpau i ka loaʻa ʻana o ka ʻoluʻolu o ka mea kūʻai aku.
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 i ka 2,5-dimethoxybenzoic acid, benzonitrile a i ʻole benzyl alcohol, 2,5-dimethoxybenzaldehyde ponoʻī nō hoʻi ka waiwai noi 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.

Ua paʻa mākou i ka hāʻawi ʻana i ka lawelawe kūʻai kūʻai maʻalahi, mālama manawa a mālama kālā no ka Personlized Products 2, 5-Dimethoxybenzaldehyde CAS 93-02-7.
Nā huahana pilikino93-02-7 a me 2 5-Dimethoxybenzaldehyde, Ke hahai nei mākou i nā hana ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i kēia mau huahana e hōʻoia i ka lōʻihi a me ka hilinaʻi o nā huahana. Ke hahai nei mākou i nā kaʻina holoi holoi maikaʻi hou loa a hiki iā mākou ke hāʻawi i ka maikaʻi ʻole o nā huahana no kā mākou mea kūʻai.
