Chemical Structure
Description
Tri(thiophen-2-yl)borane (CAS 34422-16-7) is a high-purity analytical reference standard with the molecular formula C12H9BS3 and a molecular weight of 260.21 g/mol.
Structurally, Tri(thiophen-2-yl)borane (C12H9BS3) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 260.21 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), Tri(thiophen-2-yl)borane 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.
