Chemical Structure

(2R,2'R,3R,3'R)-3,3'-di-tert-butyl-2,2'-di(pentan-3-yl) -2,2',3,3'-tetrahydro-4,4'-bi benzo[d][1,3]oxaphosphole CAS 2213449-78-4 chemical structure

Description

The occurrence of (2R,2'R,3R,3'R)-3,3'-di-tert-butyl-2,2'-di(pentan-3-yl) -2,2',3,3'-tetrahydro-4,4'-bi benzo[d][1,3]oxaphosphole is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2R,2'R,3R,3'R)-3,3'-di-tert-butyl-2,2'-di(pentan-3-yl) -2,2',3,3'-tetrahydro-4,4'-bi benzo[d][1,3]oxaphosphole (CAS 2213449-78-4), molecular formula C32H48O2P2 and molecular weight 526.67 g/mol, is a CATO reference standard with documented purity and traceability.

(2R,2'R,3R,3'R)-3,3'-di-tert-butyl-2,2'-di(pentan-3-yl) -2,2',3,3'-tetrahydro-4,4'-bi benzo[d][1,3]oxaphosphole (C32H48O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
