Chemical Structure
Description
4,4,6,6-Tetramethyl-5,6-dihydro-4H-thieno[2,3-c]pyrrole-2-carbaldehyde (C11H15NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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).
4,4,6,6-Tetramethyl-5,6-dihydro-4H-thieno[2,3-c]pyrrole-2-carbaldehyde (CAS 791591-64-5), molecular formula C11H15NOS and molecular weight 209.31 g/mol, is a CATO reference standard with documented purity and traceability.
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), 4,4,6,6-Tetramethyl-5,6-dihydro-4H-thieno[2,3-c]pyrrole-2-carbaldehyde 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.
