2-(Dimethylamino)-5-methyl-1-(naphthalen-1-yl)hex-4-en-1-one (CAS 91025-81-9) is a high-purity analytical reference standard with the molecular formula C19H23NO and a molecular weight of 281.39 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(Dimethylamino)-5-methyl-1-(naphthalen-1-yl)hex-4-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.39 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 2-(Dimethylamino)-5-methyl-1-(naphthalen-1-yl)hex-4-en-1-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.
