Description

Sodium Nitroprusside is an inorganic coordination compound with the formula Na₂[Fe(CN)₅NO]·2H₂O, widely recognized for its potent vasodilatory properties. This compound is a critical reagent in analytical chemistry and a key active pharmaceutical ingredient (API) in emergency medicine. It is essential for industries and research institutions requiring precise nitric oxide donors or cyanide detection agents. Our high-purity Sodium Nitroprusside CAS NO 14402-89-2 is manufactured under stringent controls to ensure reliability for sensitive applications.

Application

• Pharmaceutical Manufacturing: As an active pharmaceutical ingredient (API) in injectable formulations for the acute management of hypertensive crises and severe heart failure.
• Clinical Diagnostics & Research: A fundamental reagent in biochemical assays for the colorimetric detection and quantification of sulfhydryl groups (-SH), such as in glutathione and cysteine analysis.
• Analytical Chemistry: Used as a standard and reagent in methods for the determination of aldehydes, ketones, and various anions in environmental and industrial samples.
• Veterinary Medicine: Employed in controlled settings for managing blood pressure in animals during surgical procedures.
• Chemical Synthesis: Serves as a specialized source of nitrosyl (NO) and cyanide ligands in the synthesis of novel coordination compounds and catalysts.
• Educational & Laboratory Use: Supplied to academic and R&D laboratories for teaching and experimental purposes in pharmacology and inorganic chemistry.

Quality Control

Our Sodium Nitroprusside is produced and tested to meet exacting standards for pharmaceutical and analytical applications. Each batch undergoes comprehensive analysis, including identification, assay, and impurity profiling, to ensure compliance with relevant pharmacopeial monographs (e.g., USP, EP) and internal specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is strictly light-sensitive and hygroscopic; exposure to light, air, or moisture will lead to decomposition. The storage area should be well-ventilated and away from incompatible materials.
