Chemical Structure
Description
The molecular framework of Trichloro[1,1′-methylenebis[1,1-diphenylphosphine-κP]]oxorhenium (C25H22Cl3OP2Re) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO supplies Trichloro[1,1′-methylenebis[1,1-diphenylphosphine-κP]]oxorhenium (CAS 60260-17-5), a certified reference material (molecular formula C25H22Cl3OP2Re, MW 692.96 g/mol) for analytical method development and quality control.
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.
