Chemical Structure

1,2-Bis[(2R,5R)-2,5-diisopropyl-1-phospholanyl]benzene CAS 136705-65-2 chemical structure

Description

Owing to organophosphorus functionality, an aromatic ring system, 1,2-Bis[(2R,5R)-2,5-diisopropyl-1-phospholanyl]benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1,2-Bis[(2R,5R)-2,5-diisopropyl-1-phospholanyl]benzene (CAS 136705-65-2) is a high-purity analytical reference standard with the molecular formula C26H44P2 and a molecular weight of 418.58 g/mol.

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.
