Chemical Structure

2,12-Dichlorocyclododecan-1-one CAS 858830-26-9 chemical structure

Description

2,12-Dichlorocyclododecan-1-one (CAS 858830-26-9) is a high-purity analytical reference standard with the molecular formula C12H20Cl2O and a molecular weight of 251.19 g/mol.

Structurally, 2,12-Dichlorocyclododecan-1-one (C12H20Cl2O) contains 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 251.19 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.
