1 3-bis(methoxycarbonyl)-2-methyl-2-thio-pseudour（CAS# 34840-23-8)

Hoʻolauna

ʻO 1,3-Dicarboxymethyl-2-methyl-2-thioisourea, i kapa ʻia ʻo DDMTU, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

ʻAno maikaʻi:

ʻO 1,3-Dicarboxymethyl-2-methyl-2-thioisourea kahi paʻa keʻokeʻo a melemele paha. He kūpaʻa maikaʻi ma ka lumi wela a hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe polar, e like me ka wai, ka waiʻona a me nā ketones.

E hoʻohana:

Hoʻohana nui ʻia ka 1,3-Dicarboxymethyl-2-methyl-2-thioisourea i ka synthesis organik ma ke ʻano he oxidant thiomoded compound. Hiki iā ia ke hoʻokaʻawale i ka oxidation o sulfides e like me thioether, thionitrile a me thiamine e hana i nā mercaptans pili, thioketones a me nā imines.

Hanana:

ʻO ke ʻano o ka hoʻomākaukau ʻana o 1,3-dicarboxymethyl-2-methyl-2-thioisourea ka mea nui i ʻelua mau ʻanuʻu: ka hopena o ka thioglycolic acid me ka methylisourea e loaʻa ai ka 1,3-dicarboxymethyl-2-methyl-2-thioisourea; Hoʻomaʻemaʻe ʻia ka huahana i makemake ʻia e ka crystallization a i ʻole nā ​​​​ʻano hoʻomaʻemaʻe ʻē aʻe.

ʻIke palekana:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea ʻaʻohe pōʻino maopopo i ke kino kanaka a me ke kaiapuni ma lalo o nā kūlana hana maʻamau. Pono e mālama i ka hoʻopili pololei ʻana i ka ʻili a me ka inhalation o kona lepo i ka wā o ka hana. Pono e hoʻohana ʻia ma lalo o nā ʻano makani maikaʻi a pale i ka hoʻohu ʻana i kona mau mahu. Hōʻalo i ka hoʻopili ʻana me nā mea e like me nā oxidants, nā ʻakika ikaika, a me nā kumu ikaika. Ke mālama ʻia a mālama ʻia, pono e mālama ʻia i loko o kahi pahu maloʻo, ventilated a paʻa i ka ea, mai kahi ahi a me nā kumu wela. E ʻoluʻolu e nānā i nā pepa ʻikepili palekana pili a me nā ʻōlelo aʻoaʻo i ka wā e hoʻohana ai.
