Oxytetracycline dihydrate is a broad-spectrum antibiotic derived from *Streptomyces rimosus*, widely used in veterinary medicine, aquaculture, and agricultural settings to treat bacterial infections in livestock, poultry, and fish. It inhibits protein synthesis in susceptible bacteria, making it effective against gram-positive and gram-negative pathogens, as well as *Chlamydia* and *Rickettsia*. This chemical is supplied as a white to pale yellow crystalline powder with a molecular formula of C22H24N2O9·2H2O and a molecular weight of 496.46 g/mol. It must be stored at -15 to -20°C to preserve potency, with a signal word classification of "Warning" due to its moderate toxicity. Molekula supplies Oxytetracycline dihydrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
