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.

(2|A,4|A,15|A)-15-Hydroxy-2-[[2-O-(3-methyl-1-oxobutyl)-3,4-di-O-sulfo-|A-D-glucopyranosyl]oxy]-19-norkaur-16-en-18-oic Acid Disodium Salt 100938-11-2 Atractylic Acid Disodium Salt Atractylin Sodium Salt Atractyloside Disodium Salt Discontinued Sodium Atractylate (CAS 100938-11-2) is a high-purity analytical reference standard with the molecular formula C30H44O16S2Na and a molecular weight of 747.78 g/mol.

Based on its molecular formula C30H44O16S2Na, (2|A,4|A,15|A)-15-Hydroxy-2-[[2-O-(3-methyl-1-oxobutyl)-3,4-di-O-sulfo-|A-D-glucopyranosyl]oxy]-19-norkaur-16-en-18-oic Acid Disodium Salt 100938-11-2 Atractylic Acid Disodium Salt Atractylin Sodium Salt Atractyloside Disodium Salt Discontinued Sodium Atractylate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 747.78 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
