Chemical Structure
Description
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.
1,2-Bis(2,5-diisopropylphospholan-1-yl)benzene (CAS 377773-92-7) is a high-purity analytical reference standard with the molecular formula C26H44P2 and a molecular weight of 418.58 g/mol.
Structurally, 1,2-Bis(2,5-diisopropylphospholan-1-yl)benzene (C26H44P2) contains organophosphorus functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 418.58 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
