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

Folasaga

1,3-Dicarboxymethyl-2-methyl-2-thioisourea, e taʻua foi o le DDMTU, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala sauniuni ma fa'amatalaga saogalemu:

Tulaga lelei:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea o se paʻepaʻe poʻo samasama tioata tioata. E lelei le mautu i le vevela o le potu ma e mafai ona faʻamavaeina i nisi polar solvents, e pei o le vai, ava malosi ma ketones.

Fa'aaogā:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea o loʻo faʻaaogaina lautele i le faʻapipiʻiina o meaola e avea o se vailaʻau faʻamaʻi lelei thiomoded. E mafai ona faʻamalosia le faʻamaʻiina o sulfides e pei o le thioether, thionitrile ma le thiamine e maua ai le mercaptans tutusa, thioketones ma imines.

Metotia:

O le auala sauniuni o le 1,3-dicarboxymethyl-2-methyl-2-thioisourea e masani ona aofia ai laasaga e lua: o le tali atu o le thioglycolic acid ma le methylisourea e maua ai le 1,3-dicarboxymethyl-2-methyl-2-thioisourea; Ona fa'amamāina lea o le oloa fa'atatau e ala i le fa'ama'i tioata po'o isi metotia fa'amamāina.

Fa'amatalaga Saogalemu:

1,3-Dicarboxymethyl-2-methyl-2-thioisourea e leai se afaina o le tino o le tagata ma le siosiomaga i lalo o tulaga masani o galuega. E tatau ona faʻaeteete ina ia aloese mai le faʻafesoʻotaʻi tuusaʻo ma le paʻu ma le manava o lona pefu i le taimi o le taotoga. E tatau ona fa'agaioia i lalo o tulaga fa'alelei lelei ma 'alofia le manavaina o ana ausa. Aloese mai le tali atu i mea e pei o oxidants, malosi malosi, ma faavae malolosi. Pe a teuina ma taulimaina, e tatau ona teuina i totonu o se atigipusa mago, ea ma malulu, mamao ese mai le afi ma le vevela. Fa'amolemole va'ai i pepa fa'amaumauga mo le saogalemu ma fa'atonuga fa'agaioiga a'o fa'aoga.
