Chemical Structure
Description
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.
CATO supplies 1,2-Bis(5-(2-ethylhexyl)thiophen-2-yl)ethane-1,2-dione (CAS 1450879-08-9), a certified reference material (molecular formula C26H38O2S2, MW 446.71 g/mol) for analytical method development and quality control.
Structurally, 1,2-Bis(5-(2-ethylhexyl)thiophen-2-yl)ethane-1,2-dione (C26H38O2S2) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 446.71 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
