Chemical Structure

N,N-Diethyl-2,2-difluoroacetamide CAS 686-11-3 chemical structure

Description

As a certified reference material (CRM), N,N-Diethyl-2,2-difluoroacetamide 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.

CATO supplies N,N-Diethyl-2,2-difluoroacetamide (CAS 686-11-3), a certified reference material (molecular formula C6H11F2NO, MW 151.15 g/mol) for analytical method development and quality control.

Structurally, N,N-Diethyl-2,2-difluoroacetamide (C6H11F2NO) contains an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 151.15 g/mol, it falls into the medium-molecular-weight range. 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.
