Chemical Structure
Description
The occurrence of 5-Bromo-N-cyclopentyl-N-methylthiophene-2-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Bromo-N-cyclopentyl-N-methylthiophene-2-carboxamide (CAS 1090631-57-4), a certified reference material (molecular formula C11H14BrNOS, MW 288.20 g/mol) for analytical method development and quality control.
5-Bromo-N-cyclopentyl-N-methylthiophene-2-carboxamide (C11H14BrNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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), 5-Bromo-N-cyclopentyl-N-methylthiophene-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.
