Chemical Structure
Description
The occurrence of N,N'-(octane-1,8-diyl)bis(3-phenylpropanamide) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N,N'-(octane-1,8-diyl)bis(3-phenylpropanamide) (CAS 548481-86-3), molecular formula C26H36N2O2 and molecular weight 408.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, N,N'-(octane-1,8-diyl)bis(3-phenylpropanamide) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.58 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
