Chemical Structure
Description
2-(6-Methyl-2,4-dioxo-1,3-diazaspiro[4.5]decan-3-yl)-N-(4-methylbenzyl)acetamide (C19H25N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-(6-Methyl-2,4-dioxo-1,3-diazaspiro[4.5]decan-3-yl)-N-(4-methylbenzyl)acetamide (CAS 771501-68-9) is a high-purity analytical reference standard with the molecular formula C19H25N3O3 and a molecular weight of 343.42 g/mol.
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.
