Chemical Structure
Description
The occurrence of 2-(Bromomethyl)-4-chlorothiophene is closely related to sulfur-containing functionality, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(Bromomethyl)-4-chlorothiophene (CAS 1400991-44-7) is a high-purity analytical reference standard with the molecular formula C5H4BrClS and a molecular weight of 211.51 g/mol.
Structurally, 2-(Bromomethyl)-4-chlorothiophene (C5H4BrClS) contains sulfur-containing functionality, chlorine/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 211.51 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-(Bromomethyl)-4-chlorothiophene 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.
