> Tobramycin Sulfate API — Overview
Tobramycin Sulfate (CAS: 79645-27-5, also known as tobramycin sulfate API, deoxykanamycin B sulfate, nebramycin factor 6 sulfate, aminoglycoside API, and tobramycin sulfate salt) is an aminoglycoside API used in formulation, analytical-development, and research programs where local regulations permit. Suzhou Pharmaceutical Technology Co., Ltd. supplies Tobramycin Sulfate API in controlled small-batch and bulk quantities from Suzhou, China, with export to South America, Australia, New Zealand, Mexico, Canada, and worldwide markets. Export documentation: COA and MSDS standard for all orders.

> Applications
Tobramycin Sulfate is used by pharmaceutical and research organizations developing aminoglycoside formulations, reference methods, and impurity-control strategies. API supply is intended for qualified buyers who will confirm dosage form, assay method, sulfate-content approach, impurity requirements, pharmacopoeial strategy, and finished-dose registration obligations in their own markets.
Aminoglycoside formulation research
A 1999 New England Journal of Medicine randomized, placebo-controlled multicenter study evaluated intermittent aerosolized tobramycin solution in a controlled clinical research setting (N Engl J Med, doi:10.1056/NEJM199901073400104, n=520 randomized). This supports the need for carefully controlled Tobramycin Sulfate API quality in aminoglycoside formulation and analytical-development programs.
Analytical and impurity-control development
Buyers typically evaluate identity, assay, related substances, sulfate content, water content, pH, residual solvents, elemental impurities, microbial limits when required, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished dosage forms, compounded preparations, or branded medicines.
