Tylosin
1. Basic Information
Name: Tylosin
Alias: Tylosin base, Tylosin A, Macrolide veterinary antibiotic
CAS No.: 1401-69-0
Molecular Formula: C??H??NO??
Molecular Weight: 916.10
Category: Macrolide veterinary antibiotic API, livestock and poultry antibacterial raw material, animal feed additive, mycoplasma specific inhibitor
2. Physical and Chemical Properties
Physical Properties
- Appearance: White to pale yellow crystalline powder
- Odor: Faint characteristic fermentation antibiotic odor, bitter taste
- Solubility: Slightly soluble in water; soluble in methanol, ethanol, acetone, dichloromethane; hardly soluble in alkane solvents
- Melting Point: 128–132 ℃
- Specific Rotation [α]???: ?46° ~ ?52° (c=2, methanol)
- Density (predicted): 1.23 g/cm3
- Hygroscopy: Slightly hygroscopic under high humidity
- Aqueous property: Weakly alkaline aqueous solution; unstable under strong acidic conditions, easy to degrade and lose activity
Chemical Properties
- Molecular structure: 16-membered macrolide ring, containing deoxyaminosugar and mycinose side chains, multiple hydroxyl groups and ether bonds
- Antibacterial mechanism: Inhibits bacterial protein synthesis by binding to ribosome 50S subunit, highly effective against Gram-positive bacteria and mycoplasma
- Acid sensitivity: Rapid hydrolysis of glycosidic bonds under low pH, sharp decline in antibacterial activity; stable in neutral and weakly alkaline environments
- Esterification reaction: Hydroxyl groups can form tartrate, phosphate, acetate salts to improve water solubility for injection preparations
- Thermal stability: Stable below 60 ℃; high temperature above 100 ℃ accelerates decomposition
- Photostability: Light-sensitive; long-term UV irradiation darkens powder and reduces titer
- Compatibility: Compatible with neutral carriers, weak alkaline auxiliary materials; incompatible with strong acid, oxidants, penicillin, lincomycin
3. Main Application Fields

Safety Warning
Irritant antibiotic powder. Dust irritates eyes, nasal tract and respiratory tract; long-term repeated inhalation easily induces drug allergic rhinitis and skin dermatitis. All operations must be carried out in ventilated fume hood with dust-proof respirator, splash-proof goggles and chemical-resistant nitrile gloves. Avoid mixing with strong acid to prevent degradation. Waste liquid neutralized before discharge; solid waste classified as veterinary antibiotic hazardous waste disposed by licensed professional institutions. Strictly control medication withdrawal period for edible animals.
