Bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphine
Bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphine is an air-sensitive secondary diarylphosphine with the molecular formula C30H47O2P and a molecular weight of 470.67 g/mol (CAS 1173023-24-9). Its phosphorus centre carries a reactive P-H bond flanked by two bulky, electron-rich 3,5-di-tert-butyl-4-methoxyphenyl groups, making it a specialist phosphorus precursor and ligand building block for transition-metal catalysis. Tech Serve Solutions supplies and exports it worldwide as a research-grade fine chemical to catalysis, pharmaceutical and laboratory developers.

Phosphine ligand precursor
Serves as a precursor for assembling sterically demanding, electron-rich tertiary phosphine ligands. The reactive P-H bond is readily functionalised to install the diaryl phosphino group onto more elaborate ligand frameworks.
Transition-metal catalysis
Phosphines of this electron-rich, bulky aryl class are used to support transition-metal centres in homogeneous catalysis. They are of interest in palladium- and other metal-catalysed coupling and functionalisation chemistry studied in research settings.
Organophosphorus synthesis
The secondary phosphine acts as a versatile organophosphorus building block. Its P-H functionality undergoes onward transformations such as P-C bond formation, oxidation and coordination to metals.
Chemical synthesis intermediate
Used as an intermediate in multi-step organic and organometallic synthesis where a hindered, electron-rich aryl phosphorus fragment is required for downstream targets.
Laboratory reagent for research
Supplied as a reagent for laboratory and process-development research, including ligand screening, route scouting and analytical reference work under inert-atmosphere handling.

+
The CAS number is 1173023-24-9 and the molecular formula is C30H47O2P, with a molecular weight of 470.67 g/mol. It is a secondary diarylphosphine and has a reported melting point of about 114-119 degrees Celsius.
What grade and purity does Tech Serve Solutions supply?
+
Tech Serve Solutions supplies Bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphine as a research-grade fine chemical intended for synthesis and laboratory use. We do not represent it as USP, BP or EP pharmacopoeial grade. Exact assay and a current Certificate of Analysis are confirmed for each batch on request.
How should Bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphine be handled and stored?
+
Handle it as an air-sensitive secondary phosphine: work under an inert atmosphere with adequate ventilation, and use appropriate personal protective equipment including eye protection, gloves and a suitable respirator (N95/P1 type). It is classified as severely hazardous to water (WGK Germany 3), so prevent any release to drains or the environment. Store tightly closed, cool and dry away from air and oxidising agents, and always consult the current Safety Data Sheet before use; we provide an up-to-date SDS with every shipment.
How is Bis(3,5-di-tert-butyl-4-methoxyphenyl)phosphine packed, shipped and exported?
