3-nitro-4-{[1-(pyridin-2-yl)ethyl]amino}benzoic acid CAS 1154243-77-2

Description

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.

3-nitro-4-{[1-(pyridin-2-yl)ethyl]amino}benzoic acid (CAS 1154243-77-2), molecular formula C14H13N3O4 and molecular weight 287.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-nitro-4-{[1-(pyridin-2-yl)ethyl]amino}benzoic acid (C14H13N3O4) 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).

CATO manufactures 3-nitro-4-{[1-(pyridin-2-yl)ethyl]amino}benzoic 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.
