Chemical Structure
Description
3-(Trifluoromethyl)thiophene (CAS 86093-77-8), molecular formula C5H3F3S and molecular weight 152.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Trifluoromethyl)thiophene (C5H3F3S) contains sulfur-containing functionality, fluorine substitution. 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 152.14 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 3-(Trifluoromethyl)thiophene 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.
