Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Trans-4-cyano-3-fluorophenyl 4-propylcyclohexanecarboxylate (CAS 90525-57-8) is a high-purity analytical reference standard with the molecular formula C17H20FNO2 and a molecular weight of 289.34 g/mol.
The molecular framework of Trans-4-cyano-3-fluorophenyl 4-propylcyclohexanecarboxylate (C17H20FNO2) is characterized by a steroid core, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Trans-4-cyano-3-fluorophenyl 4-propylcyclohexanecarboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
