Chemical Structure

Ethyl 6-methyl-2,4-dioxoheptanoate CAS 36983-32-1 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.

Ethyl 6-methyl-2,4-dioxoheptanoate (CAS 36983-32-1), molecular formula C10H16O4 and molecular weight 200.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 6-methyl-2,4-dioxoheptanoate (C10H16O4) 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 200.23 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.
