Description

S-Nitroso-n-Acetylcysteine is a nitrosated derivative of the amino acid N-acetylcysteine, functioning as a nitric oxide (NO) donor. This compound is of significant interest in biochemical and pharmacological research due to its ability to release nitric oxide under physiological conditions, making it a valuable tool for studying NO-mediated signaling pathways. It is primarily utilized by researchers and developers in the pharmaceutical, biotechnology, and life sciences sectors for applications in cardiovascular, neurological, and anti-inflammatory research.

Application

• Biochemical Research: As a controlled nitric oxide donor for studying cell signaling, vasodilation, and neurotransmission mechanisms.
• Pharmaceutical Development: A key intermediate or reference standard in the R&D of novel therapeutics targeting nitric oxide pathways.
• Cardiovascular Studies: Used in experimental models to investigate the role of NO in blood pressure regulation and vascular function.
• Neuropharmacology: Employed in research on neurodegenerative diseases and neuroprotection where NO signaling is implicated.
• Anti-inflammatory Research: Applied in studies exploring the modulation of inflammatory responses through NO release.
• Cell Culture & In Vitro Assays: Serves as a reagent to induce or modulate NO levels in experimental biological systems.

Quality Control

Our S-Nitroso-n-Acetylcysteine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (IR, NMR), to ensure it meets the high standards required for research applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting batch-specific results for purity, assay, and related substances.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation and degradation. Allow the container to reach room temperature in a desiccator before opening to prevent moisture condensation. For long-term stability, keep the material frozen and desiccated.
