Chemical Structure

N-Ethyl-2-nitro-4-trifluoromethanesulfonylaniline CAS 1579-87-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Ethyl-2-nitro-4-trifluoromethanesulfonylaniline.

CATO supplies N-Ethyl-2-nitro-4-trifluoromethanesulfonylaniline (CAS 1579-87-9), a certified reference material (molecular formula C9H9F3N2O4S, MW 298.24 g/mol) for analytical method development and quality control.

N-Ethyl-2-nitro-4-trifluoromethanesulfonylaniline (C9H9F3N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), N-Ethyl-2-nitro-4-trifluoromethanesulfonylaniline 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.
