Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3-(2-Formylphenoxy)propyl)triphenylphosphonium bromide (CAS 17954-76-6), molecular formula C28H26O2P and molecular weight 425.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-(2-Formylphenoxy)propyl)triphenylphosphonium bromide (C28H26O2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
