Description

The occurrence of 433975-12-3 6-Ethoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde F1938-0006 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

433975-12-3 6-Ethoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde F1938-0006 (CAS 433975-12-3) is a high-purity analytical reference standard with the molecular formula C12H11NO3 and a molecular weight of 217.22 g/mol.

The molecular framework of 433975-12-3 6-Ethoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde F1938-0006 (C12H11NO3) 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. 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.
