Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl 2-(pentafluorosulfanyl)acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.15 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.
Ethyl 2-(pentafluorosulfanyl)acetate (CAS 1735-74-6) is a high-purity analytical reference standard with the molecular formula C4H7F5O2S and a molecular weight of 214.15 g/mol.
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.
As a certified reference material (CRM), Ethyl 2-(pentafluorosulfanyl)acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
