Chemical Structure

4-(9,10-Dihydrophenanthren-2-yl)butanoic acid CAS 7494-59-9 chemical structure

Description

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.

CATO supplies 4-(9,10-Dihydrophenanthren-2-yl)butanoic acid (CAS 7494-59-9), a certified reference material (molecular formula C18H18O2, MW 266.33 g/mol) for analytical method development and quality control.

The molecular framework of 4-(9,10-Dihydrophenanthren-2-yl)butanoic acid (C18H18O2) 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 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.
