For chemists and laboratory professionals working with specialized chemicals, a thorough understanding of a compound's properties and safe handling procedures is fundamental to successful and secure experimentation. Di-tert-butyl(phenyl)phosphine (CAS 32673-25-9), an organophosphorus compound, is no exception. As a supplier of this valuable chemical, we believe it's important to provide key insights into its characteristics.

Di-tert-butyl(phenyl)phosphine, also known by synonyms such as Di-t-butylphenylphosphine, typically presents as a colorless liquid. Its molecular formula is C14H23P, with a molecular weight of approximately 222.31 g/mol. The compound has a boiling point of around 124-128 °C at 10 mmHg, indicating its relatively low volatility under reduced pressure, but it is sensitive to air. This air sensitivity is a critical characteristic that dictates specific handling and storage protocols.

Due to its air sensitivity, Di-tert-butyl(phenyl)phosphine must be handled under an inert atmosphere, such as nitrogen or argon. Exposure to oxygen can lead to oxidation, degrading the compound and potentially compromising its performance in sensitive catalytic or synthetic applications. This necessitates the use of Schlenk lines, glove boxes, or other specialized inert atmosphere techniques during weighing, transfer, and reaction setup. As a responsible manufacturer and supplier, we provide comprehensive safety data sheets (SDS) that detail these requirements.

The compound's applications are primarily as a ligand in catalysis, particularly in palladium-catalyzed cross-coupling reactions, and as a valuable pharmaceutical intermediate. Its effectiveness in these roles is directly linked to maintaining its purity and reactivity, which is why proper handling is crucial. For instance, when you buy Di-tert-butyl(phenyl)phosphine for your research or production needs, ensure your facility is equipped to handle air-sensitive materials.

Storage of Di-tert-butyl(phenyl)phosphine should be in tightly sealed containers, ideally under an inert gas blanket, and kept in a cool, dry, and well-ventilated area, away from sources of ignition and incompatible materials. Refrigeration may be recommended depending on the specific product formulation and shelf-life requirements.

For procurement managers and researchers, understanding these properties is not just about safety but also about ensuring the integrity of your chemical processes. When you purchase Di-tert-butyl(phenyl)phosphine from us, you receive a product that adheres to strict quality standards. We encourage all users to consult the SDS and follow recommended procedures to maximize the compound's utility and ensure safe laboratory practices.
