Chemical Structure
Description
The occurrence of ethyl 5-bromo-2-methyl-1H-pyrrole-3-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
ethyl 5-bromo-2-methyl-1H-pyrrole-3-carboxylate (CAS 881674-39-1), molecular formula C8H14BrNO2 and molecular weight 236.11 g/mol, is a CATO reference standard with documented purity and traceability.
ethyl 5-bromo-2-methyl-1H-pyrrole-3-carboxylate (C8H14BrNO2) contains an amide 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.
CATO manufactures ethyl 5-bromo-2-methyl-1H-pyrrole-3-carboxylate 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.
