Chemical Structure
Description
CATO supplies 3-(2,4-Dimethoxybenzylidene)-3,4,5,6-tetrahydro-2,3'-bipyridine (CAS 156743-65-6), a certified reference material (molecular formula C19H20N2O2, MW 308.37 g/mol) for analytical method development and quality control.
3-(2,4-Dimethoxybenzylidene)-3,4,5,6-tetrahydro-2,3'-bipyridine (C19H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(2,4-Dimethoxybenzylidene)-3,4,5,6-tetrahydro-2,3'-bipyridine 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.
