Chemical Structure

2,2'-Selenodibenzoic acid CAS 86571-08-6 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.

2,2'-Selenodibenzoic acid (CAS 86571-08-6), molecular formula C14H10O4Se and molecular weight 321.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2'-Selenodibenzoic acid (C14H10O4Se) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
