Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 205.21 g/mol gives 3-Methoxy-4-(2-propyn-1-yloxy)benzaldehyde oxime distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methoxy-4-(2-propyn-1-yloxy)benzaldehyde oxime (CAS 385383-46-0), a certified reference material (molecular formula C11H11NO3, MW 205.21 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methoxy-4-(2-propyn-1-yloxy)benzaldehyde oxime (C11H11NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
