Chemical Structure
Description
Structurally, 4-(Tetrahydrofuran-2-yl)tetrahydro-2H-pyran-4-carboxylic acid (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.
4-(Tetrahydrofuran-2-yl)tetrahydro-2H-pyran-4-carboxylic acid (CAS 2137817-32-2) is a high-purity analytical reference standard with the molecular formula C10H16O4 and a molecular weight of 200.23 g/mol.
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.
