Compared with other compounds in its class, the molecular weight of 202.74 g/mol gives 3-(1-Chlorobutyl)-2,5-dimethylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(1-Chlorobutyl)-2,5-dimethylthiophene (CAS 1308106-91-3) is a high-purity analytical reference standard with the molecular formula C10H15ClS and a molecular weight of 202.74 g/mol.
3-(1-Chlorobutyl)-2,5-dimethylthiophene (C10H15ClS) contains sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
