Chemical Structure

1,3-diethyl 2-(cyclohex-2-en-1-yl)propanedioate CAS 6305-63-1 chemical structure

Description

The occurrence of 1,3-diethyl 2-(cyclohex-2-en-1-yl)propanedioate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-diethyl 2-(cyclohex-2-en-1-yl)propanedioate (CAS 6305-63-1), molecular formula C13H20O4 and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H20O4, 1,3-diethyl 2-(cyclohex-2-en-1-yl)propanedioate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
