Abstract
Iegūtas nitrofurantoīna kristāliskās formas: α forma, β forma, DMF I solvāts, DMF II solvāts, DMSO solvāts, DMSO/H2O solvāts un II monohidrāts. Veikta to raksturošana un stabilitātes noteikšana, izmantojot pulvera rentgendifraktometriju, diferenciāli termisko analīzi/termogravimetrija un infrasarkano spektrometriju.
Different crystal forms of nitrofurantoin were obtained: α forma, β forma, DMF I solvate, DMF II solvate, DMSO solvate, DMSO/H2O solvate and monohydrate II. Obtained crystal forms were characterized and stability determined using powder x-ray diffraction, differential thermal analysis/thermogravimetry and infrared spectroscopy.
