Trimethoprim, a kind of white or yellowish white powder, is melting at 199-203 °C. It is a lipotropy weak alkaline ethylamine pyrimidine bacteriostatic agent, called as sulfa-synergist, too. Typically, it is ordorless, tastes bitter, sparingly soluble in chloroform, slightly soluble in alcohol or acetate, and easily soluble in glacial acetic acid. But it is almost insoluble in water. Solubility in water is less than 0.1 g per 100 ml at 24 ºC.
