The chemical name of this substance is di-iod-para-phenol-sidphonic acid. It combines with bases to form salts, of which the combinations with mercury, potassium, and sodium have been used or proposed for use in medical practice. Sozoiodol contains 52 per cent of iodine, and crystallizes in prisms. It is soluble in water, alcohol, and ether.

This preparation has been introduced as a substitute for iodoform, and was first reported on in 1888 by Dr. Fritsche, since which time it has been used with a measure of success, especially in its combination with mercury. But sozoiodol has been applied in the undiluted form, and in solution in water in the treatment of rhinitis and other nasal affections, in otorrhoea, and catarrhal and ulcerative affections of the mouth and throat (Teichmann). It is an excellent antiseptic dressing for wounds and injuries, for venereal sores, and as an injection for gonorrhoea. In venereal diseases it stands in the front rank as a remedy, according to Rosinski. The combination with mercury has been used subcutaneously with much success. In fact, in the whole range of the applications of iodoform for external and internal purposes, sozoiodol may be equally applied.
