Folasaga

O le 2-mercapto-3-pyridylcarboxylic acid o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i ona meatotino, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

Tulaga lelei:

- Fa'aaliga: 2-mercapto-3-pyrolinic acid e leai se lanu e malamalama i le tioata samasama po'o le tioata tioata.

- Sogisogi: e iai sona manogi fa'apitoa.

- Soluble: Solu i le vai, ethanol ma chloroform.

Fa'aaogā:

- E mafai ona faʻaaogaina e fai ma sauniuniga mo vailaʻau faʻamaʻi, vailaʻau faʻatasi, ma vailaʻau faʻalavelave.

Metotia:

2-mercapto-3-pyrolicarboxylic acid e mafai ona saunia e:

- E tali atu le Balinomycin ma le carbamate e maua ai le mercapto-picolinate.

- Esterification tali: mercapto-picolinate e tali atu i le alkyd acid tutusa e maua ai le 2-mercapto-3-pyridylcarboxylic acid.

Fa'amatalaga Saogalemu:

- 2-mercapto-3-picolinic acid e faʻafefe. O le taimi lava e faʻafesoʻotaʻi ai le paʻu ma mata, fufulu i le tele o vai.
