-Kakaretso ea lithethefatsi: e ka sebelisoa e le selelekela bakeng sa ho qaptjoa ha lithethefatsi tse ling tse seng tsa steroidal tse khahlanong le ho ruruha le lithethefatsi tse ling.
-Indasteri ea dae: e ka sebelisoa bakeng sa lidae tsa maiketsetso le li-pigments.
Mokhoa oa ho itokisa:
3-nitro-4-bromobenzoic acid e ka lokisoa ka nitrate ea 4-bromobenzoic acid. Mehato e khethehileng ke e latelang:
1. Hlakola 4-bromobenzoic acid ka tharollo e tsoakiloeng ea nitric acid le glacial acetic acid.
2. Hlohlelletsa motsoako oa karabelo ka mocheso o tlase.
3. Sehlahisoa se entsoeng ka motsoako oa karabelo se tlhotliloeng le ho hlatsuoa, ebe se omisoa ho fumana 3-nitro-4-bromobenzoic acid.
Lintlha tsa Tšireletseho:
3-nitro-4-bromobenzoic acid e na le phello e susumetsang letlalong le mahlo, 'me e lokela ho hloekisoa ka ho feletseng ka mor'a ho kopana. Nakong ea tšebeliso le polokelo, qoba ho hema lerōle la eona 'me u apare lisebelisoa tse sireletsang haeba ho hlokahala. Ho feta moo, 3-nitro-4-bromobenzoic acid le eona e ka baka kotsi tikolohong, kahoo ho lokela ho nkoa tlhokomelo ho latela melao e nepahetseng ea polokeho ea tikoloho.
