Gentamicin Sulfate API (CAS No. 1405-41-0) is a fermentation-derived aminoglycoside antibacterial active pharmaceutical ingredient widely associated with injectable, ophthalmic, topical, and other anti-infective pharmaceutical formulations.
Gentamicin Sulfate is the sulfate salt, or mixture of sulfate salts, of antibiotic substances produced by the growth of Micromonospora purpurea.
The pharmaceutical material is a complex mixture of structurally related aminoglycoside antibiotic components. Principal gentamicin components include Gentamicin C1, Gentamicin C1a, Gentamicin C2, and related C-component substances.
Gentamicin Sulfate acts primarily by interacting with the bacterial 30S ribosomal subunit and disrupting normal bacterial protein synthesis.
Binding to the bacterial ribosome contributes to misreading of messenger RNA and the production of abnormal or nonfunctional proteins. This interference with protein synthesis contributes to bactericidal antibacterial activity against susceptible microorganisms.
Gentamicin Sulfate is the pharmaceutically important water-soluble form of Gentamicin and is widely associated with parenteral, ophthalmic, otic, and topical pharmaceutical products.
Pharmaceutical companies sourcing Gentamicin Sulfate API commonly evaluate microbiological potency, gentamicin component composition, chromatographic profile, related substances, fermentation-derived impurities, water content, sulfate characteristics, bacterial endotoxins, microbial quality, and batch-to-batch consistency.
Unlike conventional synthetic small-molecule APIs, Gentamicin Sulfate should not be evaluated only through a simple percentage HPLC assay. Antibiotic potency and component-composition testing are important quality attributes during pharmaceutical API qualification.
The USP definition specifies Gentamicin Sulfate potency equivalent to not less than 590 µg of Gentamicin per mg, calculated on the dried basis.
Swapnroop Drugs and Pharmaceuticals supplies Gentamicin Sulfate API for qualified pharmaceutical research, antibiotic formulation development, injectable pharmaceutical development, ophthalmic formulations, topical products, analytical requirements, generic drug development, and regulated pharmaceutical manufacturing requirements with product-specific quality documentation and secure pharmaceutical-grade packaging.
