Description

Carboxy-Ptio CAS NO 148819-93-6 is a specialized, high-purity chemical compound belonging to the class of nitroxide spin traps and nitric oxide (NO) scavengers. Its primary value lies in its potent and selective ability to bind and neutralize nitric oxide radicals, making it a critical research tool for studying oxidative stress and NO-mediated signaling pathways. This compound is essential for researchers and developers in the pharmaceutical, biotechnology, and life science sectors, particularly for applications in cardiovascular, neurological, and inflammatory disease research.

Application

• Biomedical Research: As a specific nitric oxide (NO) scavenger in cell culture and in vitro assay systems to study the role of NO in various physiological and pathological processes.
• Pharmaceutical Development: Used in drug discovery programs to investigate mechanisms of action and to validate targets related to oxidative stress and NO signaling.
• Diagnostic Reagent Component: Incorporated into diagnostic kits and assays designed to measure NO levels or oxidative stress markers in biological samples.
• Biochemical Tool: Employed in enzymology and molecular biology to probe the function of nitric oxide synthases (NOS) and other NO-producing enzymes.
• Material Science Research: Potential use in developing advanced materials where controlled radical chemistry or antioxidant properties are required.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our Carboxy-Ptio is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity, suitable for sensitive research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards for research chemicals, and specifications can be tailored to meet specific project requirements upon request.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and away from direct light exposure to maintain stability and purity.
