Chemical Structure
Description
2-Ethoxyethyl 2,2,2-trichloroacetate (CAS 30668-97-4), molecular formula C6H9Cl3O3 and molecular weight 235.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Ethoxyethyl 2,2,2-trichloroacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
