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 ((3S,4S)-1-chloro-4-methyl-2-oxohexan-3-yl)carbamate (CAS 161805-78-3) is a high-purity analytical reference standard with the molecular formula C12H22ClNO3 and a molecular weight of 263.76 g/mol.
Structurally, tert-Butyl ((3S,4S)-1-chloro-4-methyl-2-oxohexan-3-yl)carbamate (C12H22ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 263.76 g/mol, it falls into the medium-molecular-weight range. 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.
