Erythromycin thiocyanate

Erythromycin thiocyanate (CAS 7704-67-8), also marketed under the trade name ERYTROVET, is the thiocyanate salt form of the macrolide antibiotic erythromycin. It is used across pharmaceutical, veterinary, and agricultural sectors primarily for its antibacterial activity. The compound is effective against gram-positive organisms and select gram-negative pathogens. In veterinary medicine, it is formulated into oral and injectable preparations for the treatment of bacterial infections in livestock and poultry.

These applications include the management of respiratory and enteric diseases. Agricultural feed manufacturers incorporate it as an antimicrobial feed additive to control bacterial disease burden in commercial poultry and swine operations. Pharmaceutical and biotech manufacturers use it as an intermediate in the synthesis or salt-screening stages of erythromycin-based drug development. It also serves research and fermentation process applications where a stable salt form is required.

This material is essential for microbiological assay work and specialized laboratory studies. Erythromycin thiocyanate is supplied as a white to off-white crystalline powder available in technical and veterinary-grade specifications. Purity levels are typically confirmed by HPLC to ensure compliance with industrial requirements. Bulk quantities are standard for feed additive and pharmaceutical intermediate procurement for large-scale manufacturing needs.

Smaller research quantities are also available for biotech and laboratory applications. The product maintains stability and efficacy when stored under appropriate conditions according to standard chemical handling protocols.
