Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 463.48 g/mol gives (+/-) Etodolac Acyl--D-glucuronide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (+/-) Etodolac Acyl--D-glucuronide (CAS 79541-43-8), a certified reference material (molecular formula C23H29NO9, MW 463.48 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H29NO9, (+/-) Etodolac Acyl--D-glucuronide 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 463.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
