3-Benzylthiophene CAS 27921-48-8 chemical structure

Description

3-Benzylthiophene (CAS 27921-48-8), molecular formula C11H10S and molecular weight 174.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Benzylthiophene (C11H10S) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 174.26 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.

As a certified reference material (CRM), 3-Benzylthiophene 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.
