One object of the invention is high purity butoconazole nitrate of the formula (I) (I) containing maximum 0.1 wt % of chemical impurities, wherein at least 95% of the particles of the substance are below 75µm by diameter, whereas at least 99% of the particles are below 250µm by diameter, and process for its preparation. A pharmaceutical composition comprising as active ingredient, high purity butoconazole nitrate of specified particle size in admixture with known auxiliaries is also within the scope of the invention.
Compounds of formula (I): ##STR1## [wherein: Q represents a .dbd.CH-- group or a nitrogen atom; R.sup.1 represents a methylene group, a group of formula --CH.sub.2 CH(R.sup.3)--OCH.sub.2 -- (R.sup.3 being a substituted or unsubstituted phenyl group) or a group of formula --(CH.sub.2).sub.n --CH(R.sup.4)--O-- (n being 1 or 2 and R.sup.4 being a substituted or unsubstituted phenyl or phenylalkyl group); and A represents a group of formula --OR.sup.2 (R.sup.2 being an alkenyl group, an alkynyl group or a substituted or unsubstituted alkyl or phenyl group) or a group of formula --CH.sub.2 --XR.sup.11 (X being an oxygen or sulphur atom and R.sup.11 being an aryl or aralkyl group or, when X represents an oxygen atom, R.sup.11 being a hydrogen atom or a carbonyloxy or sulphonyloxy group) and acid addition salts and metal complexes thereof are valuable antimicrobial agents having low toxicity to humans and other animals and are especially valuable for the eradication of fungi.
