Chemical Structure
Description
As a certified reference material (CRM), 2-((2E,4E)-5-(6-((2-hydroxyethyl)(methyl)amino)naphthalen-2-yl)penta-2,4-dien-1-ylidene)malononitrile 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 2-((2E,4E)-5-(6-((2-hydroxyethyl)(methyl)amino)naphthalen-2-yl)penta-2,4-dien-1-ylidene)malononitrile (CAS 1638151-61-7), a certified reference material (molecular formula C21H19N3O, MW 329.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-((2E,4E)-5-(6-((2-hydroxyethyl)(methyl)amino)naphthalen-2-yl)penta-2,4-dien-1-ylidene)malononitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
