Chemical Structure
Description
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.
4'-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one (CAS 106754-95-4) is a high-purity analytical reference standard with the molecular formula C21H15NO5 and a molecular weight of 361.35 g/mol.
The molecular framework of 4'-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one (C21H15NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
