Chemical Structure

4,7-Dimethyl-1-oxaspiro[2.5]octane CAS 1561709-76-9 chemical structure

Description

The occurrence of 4,7-Dimethyl-1-oxaspiro[2.5]octane is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,7-Dimethyl-1-oxaspiro[2.5]octane (CAS 1561709-76-9), molecular formula C9H16O and molecular weight 140.22 g/mol, is a CATO reference standard with documented purity and traceability.

4,7-Dimethyl-1-oxaspiro[2.5]octane (C9H16O) contains a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
