Description
As a certified reference material (CRM), n-Cyclobutyl-2-fluoro-5-methylaniline 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.
n-Cyclobutyl-2-fluoro-5-methylaniline (CAS 1250698-67-9) is a high-purity analytical reference standard with the molecular formula C11H14FN and a molecular weight of 179.23 g/mol.
Structurally, n-Cyclobutyl-2-fluoro-5-methylaniline (C11H14FN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 179.23 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
