5-(3-Methoxypropanoyl)-2,2-dimethylcyclopentan-1-one CAS 1522550-87-3 chemical structure

Description

The occurrence of 5-(3-Methoxypropanoyl)-2,2-dimethylcyclopentan-1-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(3-Methoxypropanoyl)-2,2-dimethylcyclopentan-1-one (CAS 1522550-87-3), molecular formula C11H18O3 and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(3-Methoxypropanoyl)-2,2-dimethylcyclopentan-1-one (C11H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 198.26 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
