Metilamin: CH3NH2 Xususiyatlar: Monometilamin sifatida ham tanilgan, xona haroratida ammiak hidli rangsiz gaz yoki suyuqlikdir. U yonuvchan va uning bug'i havo bilan portlovchi aralashma hosil qilishi mumkin, portlash chegarasi 5% -21% (4,95% -20,75%). Nisbiy zichlik 0,662, erish nuqtasi -93,5 daraja, qaynash nuqtasi -6,3--6,7 daraja, -19,7 daraja (53,3kPa), -32,4 daraja (26,7kPa), -43,7 daraja (13,3kPa), -73,8 daraja (1,33kPa), parchalanish nuqtasi (1,33kPa) 0 daraja, avtomatik yonish nuqtasi 430 daraja, bug 'bosimi (25 daraja) 202,65Pa, kritik harorat 156,9 daraja, tanqidiy bosim 4,073kPa, sinishi indeksi 1,351. U suyultirilgandan keyin tutun hosil qiladi va ammiakdan ko'ra ko'proq ishqoriydir. Suv, etanol va efirda oson eriydi.
