Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 279.72 g/mol gives 3-Chloro-2-(3-methoxypropyl)-1-oxo-isoquinoline-4-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Chloro-2-(3-methoxypropyl)-1-oxo-isoquinoline-4-carbaldehyde (CAS 1018250-82-2), a certified reference material (molecular formula C14H14ClNO3, MW 279.72 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-2-(3-methoxypropyl)-1-oxo-isoquinoline-4-carbaldehyde (C14H14ClNO3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-Chloro-2-(3-methoxypropyl)-1-oxo-isoquinoline-4-carbaldehyde 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.
