Description

Isopropyl 5-(Diphenylphosphoryl)Pentanoate is a specialized organophosphorus compound featuring a pentanoate ester linkage and a diphenylphosphine oxide moiety. This unique structure makes it a valuable intermediate in advanced organic synthesis, particularly for constructing complex molecules with tailored properties. It is primarily sought after by research and development teams in the pharmaceutical and agrochemical industries for applications in catalysis, ligand synthesis, and the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates, especially those requiring phosphine oxide functional groups for bioactivity or as synthetic handles.
• Catalyst & Ligand Precursor: Serves as a precursor for the development of specialized phosphine-based ligands used in transition metal catalysis, such as cross-coupling reactions.
• Agrochemical Research: Used in the research and development of new pesticides and herbicides, where the organophosphorus core can contribute to the desired biological activity.
• Material Science: Intermediate for synthesizing functional polymers or additives where phosphine oxide groups can impart flame retardancy or modify material properties.
• Organic Synthesis Reagent: Employed in academic and industrial R&D for introducing phosphoryl groups into target molecules, enabling structure-activity relationship (SAR) studies.

Quality Control

Every batch of Isopropyl 5-(Diphenylphosphoryl)Pentanoate is produced under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with each shipment to guarantee consistency and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
