Chemical Structure
Description
The occurrence of Triphenyl((tetrahydrofuran-2-yl)methyl)phosphonium bromide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Triphenyl((tetrahydrofuran-2-yl)methyl)phosphonium bromide (CAS 18138-76-6) is a high-purity analytical reference standard with the molecular formula C23H25OP and a molecular weight of 348.42 g/mol.
Triphenyl((tetrahydrofuran-2-yl)methyl)phosphonium bromide (C23H25OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Triphenyl((tetrahydrofuran-2-yl)methyl)phosphonium bromide 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.
