Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 434.46 g/mol gives (9,9-Dioctyl-9H-fluoren-2-yl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(9,9-Dioctyl-9H-fluoren-2-yl)boronic acid (CAS 402790-30-1), molecular formula C29H43BO2 and molecular weight 434.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (9,9-Dioctyl-9H-fluoren-2-yl)boronic acid (C29H43BO2) is characterized by a steroid core, 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.
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.
