Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 160.24 g/mol gives 2-Phenylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Phenylthiophene (CAS 825-55-8), molecular formula C10H8S and molecular weight 160.24 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Phenylthiophene (C10H8S) 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 160.24 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Phenylthiophene 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.
