Chemical Structure
Description
The occurrence of (2,5-Dibromothiophen-3-yl)methanol 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-Dibromothiophen-3-yl)methanol (CAS 161490-95-5), a certified reference material (molecular formula C5H4Br2OS, MW 271.96 g/mol) for analytical method development and quality control.
Structurally, (2,5-Dibromothiophen-3-yl)methanol (C5H4Br2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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 271.96 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-Dibromothiophen-3-yl)methanol 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.
