Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,9-Dioxaspiro[5.5]undecan-4-yl methanesulfonate.
CATO supplies 1,9-Dioxaspiro[5.5]undecan-4-yl methanesulfonate (CAS 503551-84-6), a certified reference material (molecular formula C10H18O5S, MW 250.31 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H18O5S, 1,9-Dioxaspiro[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 250.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
