Chemical Structure
Description
The occurrence of 3,4,7,8-Tetramethyl-1,10-phenanthroline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,4,7,8-Tetramethyl-1,10-phenanthroline (CAS 1660-93-1), a certified reference material (molecular formula C16H16N2, MW 236.31 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,4,7,8-Tetramethyl-1,10-phenanthroline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3,4,7,8-Tetramethyl-1,10-phenanthroline 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.
