Chemical Structure

(E)-Kresoxim-4-hydroxy (free acid) CAS 1639810-29-9 chemical structure

Description

The occurrence of (E)-Kresoxim-4-hydroxy (free acid) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(E)-Kresoxim-4-hydroxy (free acid) (CAS 1639810-29-9) is a high-purity analytical reference standard with the molecular formula C17H29NO5 and a molecular weight of 327.42 g/mol.

The molecular framework of (E)-Kresoxim-4-hydroxy (free acid) (C17H29NO5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
