Chemical Structure
Description
CATO supplies Bis(2-chloroethoxy)-d8-methane (CAS 93966-78-0), a certified reference material (molecular formula C5H2D8Cl2O2, MW 181.09 g/mol) for analytical method development and quality control.
Structurally, Bis(2-chloroethoxy)-d8-methane (C5H2D8Cl2O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 181.09 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
