Chemical Structure

Sodium 4,4'-(3-oxo-1,3-dihydroisobenzofuran-1,1-diyl)bis(2-isopropyl-5-methylphenolate) CAS 63717-20-4 chemical structure

Description

As a certified reference material (CRM), Sodium 4,4'-(3-oxo-1,3-dihydroisobenzofuran-1,1-diyl)bis(2-isopropyl-5-methylphenolate) 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.

Sodium 4,4'-(3-oxo-1,3-dihydroisobenzofuran-1,1-diyl)bis(2-isopropyl-5-methylphenolate) (CAS 63717-20-4), molecular formula C3H10NO3PS and molecular weight 171.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium 4,4'-(3-oxo-1,3-dihydroisobenzofuran-1,1-diyl)bis(2-isopropyl-5-methylphenolate) (C3H10NO3PS) is characterized by an amide group, a sulfone group, a phosphonate group, a carboxylic acid 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.
