Chemical Structure

1,3-Bis((diisopropylphosphino)methyl)benzene CAS 193084-64-9 chemical structure

Description

1,3-Bis((diisopropylphosphino)methyl)benzene (CAS 193084-64-9) is a high-purity analytical reference standard with the molecular formula C20H36P2 and a molecular weight of 338.45 g/mol.

Structurally, 1,3-Bis((diisopropylphosphino)methyl)benzene (C20H36P2) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 338.45 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

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.
