Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3',6'-Bis(dimethylamino)-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid.
CATO supplies 3',6'-Bis(dimethylamino)-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid (CAS 150322-06-8), a certified reference material (molecular formula C25H22N2O5, MW 430.45 g/mol) for analytical method development and quality control.
The molecular framework of 3',6'-Bis(dimethylamino)-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid (C25H22N2O5) 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.
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.
CATO manufactures 3',6'-Bis(dimethylamino)-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthene]-6-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
