3-(1-(3-Chloropropyl)piperidin-4-yl)-6-fluorobenzo[d]isoxazole, 97% (CAS 329977-73-3) is a high-purity analytical reference standard with the molecular formula C15H18ClFN2O and a molecular weight of 296.77 g/mol.
The molecular framework of 3-(1-(3-Chloropropyl)piperidin-4-yl)-6-fluorobenzo[d]isoxazole, 97% (C15H18ClFN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
