16,26-Bis(diphenylphosphanyl)-3,14-dioxa-1,2(1,3)-dibenzenacyclotetradecaphane CAS 1225281-43-5 chemical structure

Description

The occurrence of 16,26-Bis(diphenylphosphanyl)-3,14-dioxa-1,2(1,3)-dibenzenacyclotetradecaphane 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.

16,26-Bis(diphenylphosphanyl)-3,14-dioxa-1,2(1,3)-dibenzenacyclotetradecaphane (CAS 1225281-43-5) is a high-purity analytical reference standard with the molecular formula C46H46O2P2 and a molecular weight of 692.80 g/mol.

16,26-Bis(diphenylphosphanyl)-3,14-dioxa-1,2(1,3)-dibenzenacyclotetradecaphane (C46H46O2P2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 16,26-Bis(diphenylphosphanyl)-3,14-dioxa-1,2(1,3)-dibenzenacyclotetradecaphane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
