1-Oxa-9-thiaspiro[5.5]undecan-4-yl methanesulfonate CAS 503551-92-6

Description

Compared with other compounds in its class, the molecular weight of 266.38 g/mol gives 1-Oxa-9-thiaspiro[5.5]undecan-4-yl methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Oxa-9-thiaspiro[5.5]undecan-4-yl methanesulfonate (CAS 503551-92-6) is a high-purity analytical reference standard with the molecular formula C10H18O4S2 and a molecular weight of 266.38 g/mol.

Based on its molecular formula C10H18O4S2, 1-Oxa-9-thiaspiro[5.5]undecan-4-yl methanesulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 266.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
