Chemical Structure

4-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride CAS 91539-64-9 chemical structure

Description

As a certified reference material (CRM), 4-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride 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.

4-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride (CAS 91539-64-9), molecular formula C21H15NO5HCl and molecular weight 397.81 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-(Aminomethyl)-3',6'-dihydroxy-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one hydrochloride (C21H15NO5HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
