Zoo:
- Cov tsos mob: 2-mercapto-3-pyrolinic acid tsis muaj xim rau lub teeb daj crystalline lossis crystalline khoom.
- hnov tsw: muaj ntxhiab tsw tshwj xeeb.
- Solubility: Soluble hauv dej, ethanol thiab chloroform.
Siv:
- Nws tuaj yeem siv los ua kev npaj rau tshuaj tua kab mob, co-solvents, thiab complexing agents.
Txoj kev:
2-mercapto-3-pyrolicarboxylic acid tuaj yeem npaj los ntawm:
- Balinomycin reacts nrog carbamate muab mercapto-picolinate.
- Esterification cov tshuaj tiv thaiv: mercapto-picolinate yog reacted nrog cov sib raug alkyd acid kom tau 2-mercapto-3-pyridylcarboxylic acid.
Cov ntaub ntawv kev nyab xeeb:
