Chemical Structure

1,3-Bis((di-tert-butylphosphino)methyl)benzene CAS 149968-36-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,3-Bis((di-tert-butylphosphino)methyl)benzene (CAS 149968-36-5), molecular formula C24H44P2 and molecular weight 394.55 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, 1,3-Bis((di-tert-butylphosphino)methyl)benzene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
