Chemical Structure
Description
The occurrence of 2,5-Dibromo-3-thiophenecarbaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dibromo-3-thiophenecarbaldehyde (CAS 1193-69-7), a certified reference material (molecular formula C5H2Br2OS, MW 269.94 g/mol) for analytical method development and quality control.
Structurally, 2,5-Dibromo-3-thiophenecarbaldehyde (C5H2Br2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 269.94 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), 2,5-Dibromo-3-thiophenecarbaldehyde 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.
