Industrial-grade 99.5% Triphenylphosphine CAS 603-35-0 TPP

Certificate of Analysis-COA 

 Applications 

1. For Homogeneous Catalysis And Cross-Coupling: Triphenylphosphine (PPh3, CAS 603-35-0) is a standard ligand for transition metal catalysts in hydrogenation, hydroformylation and cross-coupling reactions, supporting efficient and selective transformations in industrial and laboratory synthesis.

2. For Wittig Olefination: PPh3 is the classic reagent for the Wittig reaction, converting aldehydes and ketones into alkenes with defined double-bond geometry, a cornerstone transformation for agrochemical and specialty chemical synthesis.

3. For Reduction And Deoxygenation: As a versatile reducing agent, triphenylphosphine reduces peroxides, ozonides and other oxygenated intermediates, enabling deoxygenation and clean conversion to aldehydes, ketones and epoxides in organic synthesis.

4. For Mitsunobu And Named Reactions: PPh3 is an essential component of the Mitsunobu reaction for stereoselective C-C and C-O bond formation, and supports a wide range of named reactions in advanced organic chemistry.

5. Reliable Supply For Global Industry: Supplied as high-purity white crystalline powder with consistent quality, triphenylphosphine gives catalyst, agrochemical and fine chemical manufacturers a dependable organophosphorus reagent with stable supply, flexible packaging and professional technical support.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
