Boleng:

MOM-PyCO2H ke motsoako oa tlhaho o nang le kristale e tšoeu ho ea mosehla o mosehla kapa phofo ea crystalline.

 

Sebelisa:

MOM-PyCO2H e sebelisoa haholo k'hemistri ea organic synthesis 'me e sebelisoa haholo-holo e le karolo e bohareng ea motsoako oa tlhaho. E ka kenngoa ka har'a limolek'hule tsa manyolo e le sehlopha sa bohlokoa se sebetsang, kahoo se fetola thepa le mosebetsi oa molek'hule.

 

Mokhoa:

Ho lokisoa ha MOM-PyCO2H hangata ho finyelloa ka lik'hemik'hale tsa lik'hemik'hale. Mokhoa o tloaelehileng ke ho itšoara ka sodium cyanide ka methyl carbonate ho hlahisa 1-methyl-6-oxo-1,6-dihydropyridin-3-formylhydrazide, eo ka nako eo e leng oxidized ho sehlahisoa se lebisitsoeng sa MOM-PyCO2H.
