描述
CAS No. 73231-34-2
Molecular Formula: C₁₂H₁₄Cl₂FNO₄S
Appearance: White or off-white crystalline powder, odorless, bitter taste; very slightly soluble in water (≈1.3 mg/mL), slightly soluble in glacial acetic acid, soluble in methanol, ethanol, DMF, and DMSO; contains no chloramphenicol nitro group, and poses no risk of aplastic anemia.
Pharmacological Action: Amide alcohol broad-spectrum antibacterial antibiotic (animal-specific). Binds to the 50S ribosomal subunit of bacteria → inhibits peptidyl transferase → blocks peptide chain elongation → inhibits protein synthesis. Effective against Gram-negative and Gram-negative bacteria and mycoplasma, especially sensitive to *Actinobacillus pleuropneumoniae*, *Haemophilus parasuis*, *Pasteurella multocida*, *Streptococcus*, *Pasteurella multocida*, *Escherichia coli*, *Salmonella*, and *Haemophilus*; still effective against chloramphenicol-resistant strains.
Indications: Swine/bovine respiratory syndrome (APP, HPS, Pm, Mhp), avian *Escherichia coli*/Salmonella/chronic respiratory disease, bovine foot rot, aquatic *Aeromonas hydrophila* infection.
Storage Conditions: Sealed, protected from light, cool and dry place (<25℃).
