Chemical Structure
Description
As a certified reference material (CRM), (3E,5E)-3,5-Bis[(4-ethylphenyl)methylidene]-1-methylpiperidin-4-one 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.
CATO supplies (3E,5E)-3,5-Bis[(4-ethylphenyl)methylidene]-1-methylpiperidin-4-one (CAS 647031-88-7), a certified reference material (molecular formula C24H27NO, MW 345.48 g/mol) for analytical method development and quality control.
(3E,5E)-3,5-Bis[(4-ethylphenyl)methylidene]-1-methylpiperidin-4-one (C24H27NO) contains a steroid core, an amide group, 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 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.
