Description

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.

CATO supplies Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethyl]-.omega.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethoxy]- (CAS 95823-42-0), a certified reference material (molecular formula C25H24N2O8, MW 480.47 g/mol) for analytical method development and quality control.

Based on its molecular formula C25H24N2O8, Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethyl]-.omega.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethoxy]- contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 480.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Poly[oxy(methyl-1,2-ethanediyl)], .alpha.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethyl]-.omega.-[2-(5-carboxy-1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)methylethoxy]- 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.
