33289-45-1 8-Methyl-2-(thiophen-2-yl)quinoline-4-carboxylic acid DTXSID90394081 CAS 33289-45-1

Description

As a certified reference material (CRM), 33289-45-1 8-Methyl-2-(thiophen-2-yl)quinoline-4-carboxylic acid DTXSID90394081 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.

CATO supplies 33289-45-1 8-Methyl-2-(thiophen-2-yl)quinoline-4-carboxylic acid DTXSID90394081 (CAS 33289-45-1), a certified reference material (molecular formula C15H11NO2S, MW 269.32 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H11NO2S, 33289-45-1 8-Methyl-2-(thiophen-2-yl)quinoline-4-carboxylic acid DTXSID90394081 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 269.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
