Description
As a certified reference material (CRM), Benzo(B)Naphtho(2,3-D)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.
Benzo(B)Naphtho(2,3-D)Thiophene (CAS 243-46-9) is a high-purity analytical reference standard with the molecular formula C16H10S and a molecular weight of 234.32 g/mol.
Structurally, Benzo(B)Naphtho(2,3-D)Thiophene (C16H10S) contains sulfur-containing functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 234.32 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.
