Chemical Structure
Description
CATO supplies 2-Acetamido-4-methyl-N-(3-methyl-1-{[4-(methylsulfanyl)-1-oxobutan-2-yl]carbamoyl}butyl)pentanamide (CAS 136632-32-1), a certified reference material (molecular formula C19H35N3O4S, MW 401.56 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-Acetamido-4-methyl-N-(3-methyl-1-{[4-(methylsulfanyl)-1-oxobutan-2-yl]carbamoyl}butyl)pentanamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.56 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.
