Description

Streptomycin Nitrate CAS NO 3688-73-1 is the nitrate salt form of the broad-spectrum aminoglycoside antibiotic streptomycin. This compound is valued for its potent antibacterial activity, particularly against Gram-negative bacteria and *Mycobacterium tuberculosis*. It serves as a critical active pharmaceutical ingredient (API) and a key research tool in microbiology and biochemistry. Industries requiring high-purity antibiotic standards, such as pharmaceutical manufacturing, veterinary medicine, and life science research, rely on this material.

Application

• Pharmaceutical API: Used as an active ingredient in the formulation of injectable antibiotic drugs for human and veterinary use.
• Tuberculosis Treatment: A key component in combination therapies for the management of drug-susceptible tuberculosis.
• Microbiological Research: Employed as a selective agent in cell culture media to prevent bacterial contamination.
• Agricultural Applications: Used for controlling bacterial diseases in certain crops and in plant tissue culture.
• Biochemical Studies: Serves as a tool compound for studying protein synthesis inhibition and bacterial ribosome function.
• Reference Standard: Utilized as a certified reference material (CRM) in analytical laboratories for quality control and method validation.

Quality Control

Our Streptomycin Nitrate is manufactured and tested under a strict quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for pharmaceutical and research applications. Specifications typically align with pharmacopeial monographs (e.g., USP, EP). A comprehensive Certificate of Analysis (COA) detailing purity, potency, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
