Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 439411S4TB 579-92-0 Diphenylamine-2,2'-dicarboxylic acid Benzoic acid, 2,2'-iminobis- (9CI) Benzoic acid, 2,2'-iminodi- 4-14-00-01058 (Beilstein Handbook Reference) Anthranilic acid, N-(o-carboxyphenyl)- BRN 0483973 2,2'-Dicarboxydiphenylamine 2,2'-Dicarboxyldiphenylamine 2,2'-Diphenylaminedicarboxylic acid 2,2'-Iminodibenzoic acid NSC 27841 Vanadox UNII-439411S4TB.

CATO supplies 439411S4TB 579-92-0 Diphenylamine-2,2'-dicarboxylic acid Benzoic acid, 2,2'-iminobis- (9CI) Benzoic acid, 2,2'-iminodi- 4-14-00-01058 (Beilstein Handbook Reference) Anthranilic acid, N-(o-carboxyphenyl)- BRN 0483973 2,2'-Dicarboxydiphenylamine 2,2'-Dicarboxyldiphenylamine 2,2'-Diphenylaminedicarboxylic acid 2,2'-Iminodibenzoic acid NSC 27841 Vanadox UNII-439411S4TB (CAS 579-92-0), a certified reference material (molecular formula C14H23NO4, MW 269.34 g/mol) for analytical method development and quality control.

The molecular framework of 439411S4TB 579-92-0 Diphenylamine-2,2'-dicarboxylic acid Benzoic acid, 2,2'-iminobis- (9CI) Benzoic acid, 2,2'-iminodi- 4-14-00-01058 (Beilstein Handbook Reference) Anthranilic acid, N-(o-carboxyphenyl)- BRN 0483973 2,2'-Dicarboxydiphenylamine 2,2'-Dicarboxyldiphenylamine 2,2'-Diphenylaminedicarboxylic acid 2,2'-Iminodibenzoic acid NSC 27841 Vanadox UNII-439411S4TB (C14H23NO4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
