Chemical Structure

2-Hydroxyimino-N-(3-trifluoromethyl-phenyl)-acetamide CAS 404-83-1 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 2-Hydroxyimino-N-(3-trifluoromethyl-phenyl)-acetamide.

2-Hydroxyimino-N-(3-trifluoromethyl-phenyl)-acetamide (CAS 404-83-1), molecular formula C9H7F3N2O2 and molecular weight 232.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Hydroxyimino-N-(3-trifluoromethyl-phenyl)-acetamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 2-Hydroxyimino-N-(3-trifluoromethyl-phenyl)-acetamide 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.
