Chemical Structure

tert-Butyl 3-(2-phenylacetyl)benzylcarbamate CAS 1017781-86-0 chemical structure

Description

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.

tert-Butyl 3-(2-phenylacetyl)benzylcarbamate (CAS 1017781-86-0), molecular formula C20H23NO3 and molecular weight 325.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, tert-Butyl 3-(2-phenylacetyl)benzylcarbamate (C20H23NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 325.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
