Description
As a certified reference material (CRM), 2-Bromo-3-nonylthiophene 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.
2-Bromo-3-nonylthiophene (CAS 1398044-31-9), molecular formula C13H21BrS and molecular weight 289.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-3-nonylthiophene (C13H21BrS) contains sulfur-containing functionality, bromine 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 289.27 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.
