Tylosin tartrate

Tylosin tartrate (CAS 74610-55-2), also marketed under the trade names Pharmasin, Tylan Soluble, and Tylan Injectable, is the tartrate salt form of the macrolide antibiotic tylosin. It is used in veterinary medicine and animal production as an antimicrobial agent to control bacterial infections and support growth performance in livestock across various agricultural sectors.

In swine and poultry production, this compound is incorporated into medicated feed and drinking water formulations to treat and prevent respiratory and enteric infections caused by Mycoplasma. Cattle and sheep producers use injectable formulations to manage pneumonia and soft tissue infections in individual animals. The compound also serves as a reference standard and active pharmaceutical ingredient.

Consistent potency and purity are critical for batch release in veterinary drug manufacturing. Research applications include use as a positive control in antimicrobial susceptibility testing protocols for laboratories. The product is supplied as a water-soluble powder, suited for both oral solution and premix manufacturing. It is available in pharmaceutical-grade and veterinary-grade specifications for industrial use.

Potency is typically expressed in units per milligram against established reference standards. Bulk quantities are standard for feed additive manufacturers, while smaller packaging supports compounding pharmacies.
