The occurrence of 1-(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)heptane-1,6-dione is closely related to a sulfone group, 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-(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)heptane-1,6-dione (CAS 898772-68-4), molecular formula C14H18O4S and molecular weight 282.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)heptane-1,6-dione (C14H18O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 282.36 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.
