Chemical Structure

Ethyl 3,3,3-trifluoro-2-(hydroxyimino)propanoate CAS 263750-66-9 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 Ethyl 3,3,3-trifluoro-2-(hydroxyimino)propanoate.

CATO supplies Ethyl 3,3,3-trifluoro-2-(hydroxyimino)propanoate (CAS 263750-66-9), a certified reference material (molecular formula C5H6F3NO3, MW 185.10 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H6F3NO3, Ethyl 3,3,3-trifluoro-2-(hydroxyimino)propanoate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 185.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
