Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-Ethoxy-5-methylphenyl)ethan-1-one (CAS 857277-13-5) is a high-purity analytical reference standard with the molecular formula C11H14O2 and a molecular weight of 178.23 g/mol.
The molecular framework of 1-(2-Ethoxy-5-methylphenyl)ethan-1-one (C11H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
As a certified reference material (CRM), 1-(2-Ethoxy-5-methylphenyl)ethan-1-one 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.
