Chemical Structure
Description
As a certified reference material (CRM), 3-Cyclobutoxy-4-fluorobenzaldehyde 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.
CATO supplies 3-Cyclobutoxy-4-fluorobenzaldehyde (CAS 1820606-99-2), a certified reference material (molecular formula C11H11FO2, MW 194.20 g/mol) for analytical method development and quality control.
The molecular framework of 3-Cyclobutoxy-4-fluorobenzaldehyde (C11H11FO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.
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.
