Chemical Structure
Description
The molecular framework of 1,2-Difluoro-4-((1S,4R)-4-(2-((1S,4S)-4-propylcyclohexyl)ethyl)cyclohexyl)benzene (C23H34F2) is characterized by fluorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1,2-Difluoro-4-((1S,4R)-4-(2-((1S,4S)-4-propylcyclohexyl)ethyl)cyclohexyl)benzene (CAS 117943-37-0) is a high-purity analytical reference standard with the molecular formula C23H34F2 and a molecular weight of 348.51 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,2-Difluoro-4-((1S,4R)-4-(2-((1S,4S)-4-propylcyclohexyl)ethyl)cyclohexyl)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.
