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-N-phenyl-1H-pyrrole-2-carboxamide.
4-Bromo-N-phenyl-1H-pyrrole-2-carboxamide (CAS 940738-66-9) is a high-purity analytical reference standard with the molecular formula C11H9BrN2O and a molecular weight of 265.11 g/mol.
4-Bromo-N-phenyl-1H-pyrrole-2-carboxamide (C11H9BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-N-phenyl-1H-pyrrole-2-carboxamide 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.
