Florfenicol Key Intermediate D-ester

Florfenicol Key Intermediate D-ester

D-p-methylsulfonylphenylserine ethyl ester (referred to as D-ester) is a chiral aromatic o-aminoalcohol compound with a white or off-white crystalline powder appearance. It is an indispensable key chiral intermediate in the synthesis of the third-generation chloramphenicol broad-spectrum veterinary antibiotic florfenicol.

Product specifications

Application oneSynthesis of florfenicol API: used for the production of veterinary injections, soluble powders, premixes and other preparations
Application twoLivestock and poultry disease prevention and control: used for the treatment of respiratory and digestive tract infections and bacterial sepsis in pigs, cattle, chickens and other livestock and poultry
Application threeAquaculture disease prevention and control: used for the prevention and treatment of bacterial gill rot, red skin disease, enteritis and vibriosis in fish, shrimp and crabs

As a core high-value raw material in the upstream of the veterinary drug industry chain, D-ester is exclusively used in the field of animal-specific antibiotic synthesis, and can serve industries such as prevention and control of bacterial diseases in livestock, poultry and aquatic animals, comprehensive disease solutions for the breeding industry, and animal health API production.

Key application areas

  • Synthesis of florfenicol API: As a core precursor, florfenicol API is prepared through chemical reactions such as acylation, which can be used in the production of veterinary injections, soluble powders, premixes and other preparations.
  • Livestock and poultry disease prevention and control: Eventually converted into florfenicol finished product, used for the treatment of respiratory diseases, digestive tract infections and bacterial sepsis in pigs, cattle, chickens and other livestock and poultry.
  • Aquaculture disease prevention and control: Suitable for prevention and control of bacterial gill rot, red skin disease, enteritis and vibriosis in fish, shrimps and crabs.
