Chemical Structure

(3aR,5R,6R,6aR)-6-Hydroxy-5-(hydroxymethyl)tetrahydrofuro[3,2-b]furan-2(3H)-one CAS 189556-51-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 174.15 g/mol gives (3aR,5R,6R,6aR)-6-Hydroxy-5-(hydroxymethyl)tetrahydrofuro[3,2-b]furan-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3aR,5R,6R,6aR)-6-Hydroxy-5-(hydroxymethyl)tetrahydrofuro[3,2-b]furan-2(3H)-one (CAS 189556-51-2), molecular formula C7H10O5 and molecular weight 174.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3aR,5R,6R,6aR)-6-Hydroxy-5-(hydroxymethyl)tetrahydrofuro[3,2-b]furan-2(3H)-one (C7H10O5) 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 174.15 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
