Chemical Structure

tert-Butyl (2-methyl-4-oxopentan-2-yl)carbamate CAS 133466-99-6 chemical structure

Description

The molecular framework of tert-Butyl (2-methyl-4-oxopentan-2-yl)carbamate (C11H21NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

tert-Butyl (2-methyl-4-oxopentan-2-yl)carbamate (CAS 133466-99-6) is a high-purity analytical reference standard with the molecular formula C11H21NO3 and a molecular weight of 215.29 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.
