Chemical Structure

3-Ethyl-1-oxa-4-azaspiro[5.5]Undecane CAS 1481082-03-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-1-oxa-4-azaspiro[5.5]Undecane.

CATO supplies 3-Ethyl-1-oxa-4-azaspiro[5.5]Undecane (CAS 1481082-03-4), a certified reference material (molecular formula C11H21NO, MW 183.29 g/mol) for analytical method development and quality control.

Structurally, 3-Ethyl-1-oxa-4-azaspiro[5.5]Undecane (C11H21NO) contains an amide group, a hydroxyl group, an ether linkage. 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 183.29 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.

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.
