3-(5-Hydroxy-1-oxo-1,2-dihydroisoquinolin-4-yl)benzaldehyde CAS 656234-28-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(5-Hydroxy-1-oxo-1,2-dihydroisoquinolin-4-yl)benzaldehyde.

3-(5-Hydroxy-1-oxo-1,2-dihydroisoquinolin-4-yl)benzaldehyde (CAS 656234-28-5) is a high-purity analytical reference standard with the molecular formula C16H11NO3 and a molecular weight of 265.26 g/mol.

Based on its molecular formula C16H11NO3, 3-(5-Hydroxy-1-oxo-1,2-dihydroisoquinolin-4-yl)benzaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 265.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-(5-Hydroxy-1-oxo-1,2-dihydroisoquinolin-4-yl)benzaldehyde 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.
