2. Solubility: Ikhoza kusungunuka mu zosungunulira zambiri za organic, monga ma alcohols, ethers, chlorinated hydrocarbons, etc.
3. Malo osungunuka ndi malo owira: Malo osungunuka a METHYL 5,6-dichloronicotinate ndi pafupifupi 68-71 digiri Celsius, ndipo malo owira ndi pafupifupi 175 digiri Celsius.
Gwiritsani ntchito:
1.METHYL 5,6-dichloronicotinate angagwiritsidwe ntchito ngati wapakatikati mu kaphatikizidwe organic ndi ntchito kaphatikizidwe zina organic mankhwala.
2. Itha kugwiritsidwanso ntchito m'minda ya mankhwala ophera tizilombo, mankhwala ndi utoto.
Njira:
The kaphatikizidwe njira METHYL 5,6-dichloronicotinate chingapezeke mwa njira zotsatirazi:
1. Choyamba, nicotinic acid (nicotinic acid) imakhudzidwa ndi thionyl chloride (thionyl chloride) kupanga nicotinic acid chloride (nicotinoyl chloride).
2. Kenako, nicotinic acid chloride imapangidwa ndi methanol kupanga METHYL 5,6-dichloronicotinate.
Zambiri Zachitetezo:
1. METHYL 5,6-dichloronicotinate ndi organic compound yomwe imakwiyitsa. Pewani kukhudzana mwachindunji ndi khungu ndi maso mukamagwiritsa ntchito kapena kukhudzana.
2. Panthawi yogwira ntchito, m'pofunika kuonetsetsa kuti mpweya wabwino umakhala wabwino komanso kupewa kutulutsa nthunzi yake.
3. Posunga ndikugwira, ziyenera kukhala kutali ndi moto ndi okosijeni.
4. Ngati mwakoka mpweya mwangozi kapena kukhudza, nthawi yomweyo tsitsani malo omwe akhudzidwawo ndi madzi ambiri ndikupempha thandizo lachipatala.
5. Mukamagwiritsa ntchito METHYL 5,6-dichloronicotinate, Chonde tsatirani mosamalitsa njira zoyendetsera chitetezo ndi njira zodzitetezera.
