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-Bromo-2-(bromomethyl)thiophene.
4-Bromo-2-(bromomethyl)thiophene (CAS 79757-98-5) is a high-purity analytical reference standard with the molecular formula C5H4Br2S and a molecular weight of 255.96 g/mol.
4-Bromo-2-(bromomethyl)thiophene (C5H4Br2S) contains sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Bromo-2-(bromomethyl)thiophene 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.
