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.
CATO supplies Ethyl 6-(difluoromethoxy)-2,3,4,9-tetrahydro-1H-carbazole-1-carboxylate (CAS 871586-76-4), a certified reference material (molecular formula C16H17F2NO3, MW 309.31 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 6-(difluoromethoxy)-2,3,4,9-tetrahydro-1H-carbazole-1-carboxylate (C16H17F2NO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Ethyl 6-(difluoromethoxy)-2,3,4,9-tetrahydro-1H-carbazole-1-carboxylate 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.
