Chemical Structure

Xylenol Orange Sodium Salt CAS 63721-83-5 chemical structure

Description

Xylenol Orange Sodium Salt (CAS 63721-83-5) is a high-purity analytical reference standard with the molecular formula C31H31N2O13SNa and a molecular weight of 694.64 g/mol.

The molecular framework of Xylenol Orange Sodium Salt (C31H31N2O13SNa) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.

CATO manufactures Xylenol Orange Sodium Salt 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.
