1-Ethoxy-2,3-difluoro-4-((4-(4-pentylcyclohexyl)phenyl)ethynyl)benzene CAS 124770-59-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 410.54 g/mol gives 1-Ethoxy-2,3-difluoro-4-((4-(4-pentylcyclohexyl)phenyl)ethynyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Ethoxy-2,3-difluoro-4-((4-(4-pentylcyclohexyl)phenyl)ethynyl)benzene (CAS 124770-59-8), molecular formula C27H32F2O and molecular weight 410.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Ethoxy-2,3-difluoro-4-((4-(4-pentylcyclohexyl)phenyl)ethynyl)benzene (C27H32F2O) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
