Chemical Structure
Description
CATO supplies Tert-butyl (1S,6R)-8-((R)-1-phenylethyl)-3,8-diazabicyclo[4.2.0]Octane-3-carboxylate (CAS 923956-64-3), a certified reference material (molecular formula C19H28N2O2, MW 316.44 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tert-butyl (1S,6R)-8-((R)-1-phenylethyl)-3,8-diazabicyclo[4.2.0]Octane-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.44 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.
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.
