Description

Tulathromycin A CAS NO 217500-96-4 is a potent, semi-synthetic macrolide antibiotic belonging to the triamilide subclass. It is a critical active pharmaceutical ingredient (API) valued for its broad-spectrum efficacy against key respiratory pathogens in veterinary medicine. This compound is essential for manufacturers developing long-acting injectable formulations for the treatment and control of bovine and swine respiratory diseases.

Application

• Veterinary Pharmaceutical API: Primary active ingredient in long-acting injectable antibiotic formulations.
• Bovine Respiratory Disease (BRD) Treatment: Used in products for the treatment of BRD associated with *Mannheimia haemolytica*, *Pasteurella multocida*, *Histophilus somni*, and *Mycoplasma bovis*.
• Swine Respiratory Disease (SRD) Control: Key component in medications for the control of SRD associated with *Actinobacillus pleuropneumoniae*, *Pasteurella multocida*, *Mycoplasma hyopneumoniae*, and *Haemophilus parasuis*.
• Research & Development: Serves as a high-purity reference standard for analytical method development, quality control, and pharmacokinetic studies.
• Veterinary Generic Drug Manufacturing: Sourced by generic animal health companies for product development and commercialization.
• Premix and Feed Additive Development: Investigational use in developing oral administration routes, though injectable forms are dominant.
