Chemical Structure
Description
As a certified reference material (CRM), 4-Oxo-4-(phenanthren-9-yl)butanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Oxo-4-(phenanthren-9-yl)butanoic acid (CAS 68151-15-5) is a high-purity analytical reference standard with the molecular formula C18H14O3 and a molecular weight of 278.30 g/mol.
The molecular framework of 4-Oxo-4-(phenanthren-9-yl)butanoic acid (C18H14O3) 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.
