Chemical Structure
Description
CATO supplies 4-(2-(Thiophen-2-yl)ethyl)-1-oxa-4,9-diazaspiro[5.5]undecane (CAS 1708178-94-2), a certified reference material (molecular formula C14H22N2OS, MW 266.40 g/mol) for analytical method development and quality control.
4-(2-(Thiophen-2-yl)ethyl)-1-oxa-4,9-diazaspiro[5.5]undecane (C14H22N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
