N-[(1E)-{[(2-fluorophenyl)methoxy]imino}methyl]-4-methoxy-2-phenoxypyridine-3-carboxamide CAS 478262-42-9 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-[(1E)-{[(2-fluorophenyl)methoxy]imino}methyl]-4-methoxy-2-phenoxypyridine-3-carboxamide.

N-[(1E)-{[(2-fluorophenyl)methoxy]imino}methyl]-4-methoxy-2-phenoxypyridine-3-carboxamide (CAS 478262-42-9) is a high-purity analytical reference standard with the molecular formula C21H18FN3O4 and a molecular weight of 395.38 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-[(1E)-{[(2-fluorophenyl)methoxy]imino}methyl]-4-methoxy-2-phenoxypyridine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 395.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-[(1E)-{[(2-fluorophenyl)methoxy]imino}methyl]-4-methoxy-2-phenoxypyridine-3-carboxamide 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.
