Chemical Structure
Description
3,5-Difluoro-4-(isopentyloxy)benzenethiol (CAS 1443350-41-1) is a high-purity analytical reference standard with the molecular formula C11H14F2OS and a molecular weight of 232.29 g/mol.
Structurally, 3,5-Difluoro-4-(isopentyloxy)benzenethiol (C11H14F2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 232.29 g/mol, it falls into the medium-molecular-weight range. 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.
