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 N-(4-bromo-2-nitro-5-(trifluoromethyl)phenyl)acetamide.
N-(4-bromo-2-nitro-5-(trifluoromethyl)phenyl)acetamide (CAS 157554-76-2), molecular formula C9H6BrF3N2O3 and molecular weight 327.05 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-bromo-2-nitro-5-(trifluoromethyl)phenyl)acetamide (C9H6BrF3N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, 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).
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), N-(4-bromo-2-nitro-5-(trifluoromethyl)phenyl)acetamide 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.
