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 3-Bromo-2-methylthiophene.
3-Bromo-2-methylthiophene (CAS 30319-05-2) is a high-purity analytical reference standard with the molecular formula C5H5BrS and a molecular weight of 177.06 g/mol.
Based on its molecular formula C5H5BrS, 3-Bromo-2-methylthiophene contains sulfur-containing functionality, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 177.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 3-Bromo-2-methylthiophene 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.
