Chemical Structure
Description
As a certified reference material (CRM), methyl 4-bromothieno[2,3-c]pyridine-2-carboxylate 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.
methyl 4-bromothieno[2,3-c]pyridine-2-carboxylate (CAS 145325-40-2), molecular formula C9H14BrNO2S and molecular weight 280.18 g/mol, is a CATO reference standard with documented purity and traceability.
methyl 4-bromothieno[2,3-c]pyridine-2-carboxylate (C9H14BrNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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.
