Chemical Structure
Description
The occurrence of 4-Butyltetrahydro-2H-thiopyran is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Butyltetrahydro-2H-thiopyran (CAS 66625-24-9), molecular formula C9H18S and molecular weight 158.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Butyltetrahydro-2H-thiopyran (C9H18S) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
