Diphenyl carbonate CAS 102-09-0 ndi yoyera ya crystalline yolimba. Sasungunuke m'madzi, sungunuka mu ethanol yotentha, benzene, ether, carbon tetrachloride, glacial acetic acid ndi zosungunulira zina.
Benzyl mowa CAS 100-51-6 angagwiritsidwe ntchito biochemical reagents ndi intermediates mankhwala.
3,5-Difluoroaniline CAS 372-39-4 ndi kristalo wopanda mtundu wotuwa wachikasu. Angagwiritsidwe ntchito ngati mankhwala, mankhwala, intermediates mankhwala.
2-Furoic acid CAS 88-14-2 ndi woyera monoclinic rhombohedral crystal, sungunuka pang'ono m'madzi ozizira, osungunuka m'madzi otentha, ethanol ndi ether. Itha kugwiritsidwa ntchito popanga methyl furan, furfuramide ndi furoate esters ndi mchere; mu mapulasitiki Itha kugwiritsidwa ntchito ngati plasticizer, thermosetting resin, etc. mu makampani chemicalbook; monga chosungira m'makampani azakudya; itha kugwiritsidwanso ntchito ngati chapakatikati pazowonjezera zopaka utoto, mankhwala ndi zonunkhira, ndi zina.
3-Methyl-2-nitrophenol CAS 4920-77-8 ndi kristalo wachikasu. Malo osungunuka 37-39 â. Ndiwochokera ku nitrophenol ngati wothandizira antineoplastic.
Nicotinamide CAS 98-92-0 ndi singano yoyera ngati kristalo kapena ufa wa crystalline, wopanda fungo kapena wonunkhira pang'ono, wokhala ndi kukoma kowawa pang'ono. Kuchulukana kwachibale ndi 1.4, ndipo malo osungunuka ndi 129-131 ° C. 1g ya mankhwalawa imasungunuka m'madzi 1mL, 1.5mL ethanol kapena 10mL glycerol, koma osasungunuka mu ether. PH ya 10% yankho lamadzi ndi 6.5 - Chemicalbook 7.5. Ali ndi hygroscopicity yofooka. Ndiwokhazikika, osamva asidi, alkali komanso kutentha kwambiri. Ndiwokhazikika pakuwala ndi kutentha mumlengalenga wouma, ndipo nicotinic acid imapangidwa ikatenthedwa mumchere wamchere kapena acidic solution. Rat oral LD502.5-3.5g/kg, mtengo wa ADI sumapanga zinthu zapadera (ECC, 1990).
