519-57-3 8NA53C271Z Sulochrin Benzoic acid, 2-(2,6-dihydroxy-4-methylbenzoyl)-5-hydroxy-3-methoxy-, methyl ester UNII-8NA53C271Z CAS 519-57-3 chemical structure

Description

Structurally, 519-57-3 8NA53C271Z Sulochrin Benzoic acid, 2-(2,6-dihydroxy-4-methylbenzoyl)-5-hydroxy-3-methoxy-, methyl ester UNII-8NA53C271Z (C17H16O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 332.30 g/mol, it falls into the moderately-high-molecular-weight range. 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).

CATO supplies 519-57-3 8NA53C271Z Sulochrin Benzoic acid, 2-(2,6-dihydroxy-4-methylbenzoyl)-5-hydroxy-3-methoxy-, methyl ester UNII-8NA53C271Z (CAS 519-57-3), a certified reference material (molecular formula C17H16O7, MW 332.30 g/mol) for analytical method development and quality control.

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.
