5-Methyl-7-chloro-8-hydroxy-quinoline CAS 90799-56-7

Description

The occurrence of 5-Methyl-7-chloro-8-hydroxy-quinoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Methyl-7-chloro-8-hydroxy-quinoline (CAS 90799-56-7) is a high-purity analytical reference standard with the molecular formula C10H8ClNO and a molecular weight of 193.63 g/mol.

Structurally, 5-Methyl-7-chloro-8-hydroxy-quinoline (C10H8ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 193.63 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 5-Methyl-7-chloro-8-hydroxy-quinoline 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.
