2,5,8-Trimethoxy-4-methylquinoline CAS 66570-51-2

Description

2,5,8-Trimethoxy-4-methylquinoline (CAS 66570-51-2) is a high-purity analytical reference standard with the molecular formula C14H8Cl4 and a molecular weight of 318.03 g/mol.

Owing to chlorine substitution, a polycyclic aromatic system, 2,5,8-Trimethoxy-4-methylquinoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,5,8-Trimethoxy-4-methylquinoline 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.
