(2Z)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}ethyl)-3-[(4-methoxyphenyl)amino]-N-methyl-2-phenylprop-2-enamide CAS 337919-79-6 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 (2Z)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}ethyl)-3-[(4-methoxyphenyl)amino]-N-methyl-2-phenylprop-2-enamide.

(2Z)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}ethyl)-3-[(4-methoxyphenyl)amino]-N-methyl-2-phenylprop-2-enamide (CAS 337919-79-6) is a high-purity analytical reference standard with the molecular formula C25H23ClF3N3O3 and a molecular weight of 505.92 g/mol.

Based on its molecular formula C25H23ClF3N3O3, (2Z)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}ethyl)-3-[(4-methoxyphenyl)amino]-N-methyl-2-phenylprop-2-enamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 505.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), (2Z)-N-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}ethyl)-3-[(4-methoxyphenyl)amino]-N-methyl-2-phenylprop-2-enamide 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.
