Compared with other compounds in its class, the molecular weight of 196.35 g/mol gives 3-Octylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Octylthiophene (CAS 65016-62-8), molecular formula C12H20S and molecular weight 196.35 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Octylthiophene (C12H20S) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 196.35 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.
As a certified reference material (CRM), 3-Octylthiophene 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.
