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-Ethoxy-2,3-difluoro-4-(((1s,4r)-4-propylcyclohexyl)methoxy)benzene (CAS 875468-59-0), molecular formula C18H26F2O2 and molecular weight 312.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Ethoxy-2,3-difluoro-4-(((1s,4r)-4-propylcyclohexyl)methoxy)benzene (C18H26F2O2) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. 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-Ethoxy-2,3-difluoro-4-(((1s,4r)-4-propylcyclohexyl)methoxy)benzene 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.
