Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4,5-Dibromothiophen-3-yl)methanol.
CATO supplies (4,5-Dibromothiophen-3-yl)methanol (CAS 73919-89-8), a certified reference material (molecular formula C5H4Br2OS, MW 271.96 g/mol) for analytical method development and quality control.
Structurally, (4,5-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. 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.
