Description
CATO manufactures 4-bromo-5-methyl-thiophene-2-carbaldehyde 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.
4-bromo-5-methyl-thiophene-2-carbaldehyde (CAS 29421-75-8), molecular formula C6H9BrOS and molecular weight 209.10 g/mol, is a CATO reference standard with documented purity and traceability.
4-bromo-5-methyl-thiophene-2-carbaldehyde (C6H9BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
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.
