3-(((5-Ethyl-1,3,4-thiadiazol-2-yl)amino)methylene)-1,5-dioxaspiro[5.5]undecane-2,4-dione CAS 1105242-44-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(((5-Ethyl-1,3,4-thiadiazol-2-yl)amino)methylene)-1,5-dioxaspiro[5.5]undecane-2,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

3-(((5-Ethyl-1,3,4-thiadiazol-2-yl)amino)methylene)-1,5-dioxaspiro[5.5]undecane-2,4-dione (CAS 1105242-44-1), molecular formula C14H17N3O4S and molecular weight 323.37 g/mol, is a CATO reference standard with documented purity and traceability.

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.
