Description

Doxycycline CAS NO 7264-10-0 is a broad-spectrum, semi-synthetic tetracycline antibiotic. It is valued for its high potency, excellent bioavailability, and effectiveness against a wide range of gram-positive and gram-negative bacteria, as well as atypical pathogens. This makes it a critical active pharmaceutical ingredient (API) for manufacturers in the pharmaceutical, veterinary medicine, and research sectors requiring a reliable and high-quality antibiotic compound.

Application

• Human Pharmaceutical Formulations: Primary API for oral capsules, tablets, and injectables to treat respiratory infections, Lyme disease, acne, and malaria prophylaxis.
• Veterinary Medicinal Products: Key ingredient in treatments for bacterial infections in livestock, poultry, pets, and aquaculture.
• Research & Development: Used as a standard or tool compound in microbiological studies, antibiotic resistance research, and molecular biology.
• Reference Standard: Serves as a high-purity analytical standard for quality control testing in pharmaceutical laboratories.
