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 Methyl 5-(bromomethyl)thiophene-2-carboxylate, 97%.
Methyl 5-(bromomethyl)thiophene-2-carboxylate, 97% (CAS 108499-32-7), molecular formula C7H7BrO2S and molecular weight 235.10 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 5-(bromomethyl)thiophene-2-carboxylate, 97% (C7H7BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), Methyl 5-(bromomethyl)thiophene-2-carboxylate, 97% 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.
