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-(methoxymethyl)thiophene.
4-bromo-2-(methoxymethyl)thiophene (CAS 141832-35-1), molecular formula C6H7BrOS and molecular weight 207.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 4-bromo-2-(methoxymethyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-bromo-2-(methoxymethyl)thiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
