Description
As a certified reference material (CRM), 1H-Thieno[3,4-d]imidazole-4-pentanamide, hexahydro-N-(5-hydroxypentyl)-2-oxo-, [3aS-(3aa,4,6aa)]- (9CI), 95% 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.
1H-Thieno[3,4-d]imidazole-4-pentanamide, hexahydro-N-(5-hydroxypentyl)-2-oxo-, [3aS-(3aa,4,6aa)]- (9CI), 95% (CAS 181272-15-1), molecular formula C15H27N3O3S and molecular weight 329.46 g/mol, is a CATO reference standard with documented purity and traceability.
1H-Thieno[3,4-d]imidazole-4-pentanamide, hexahydro-N-(5-hydroxypentyl)-2-oxo-, [3aS-(3aa,4,6aa)]- (9CI), 95% (C15H27N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
