3-Amino-4-nitro-2-naphthoic acid CAS 498546-32-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-4-nitro-2-naphthoic acid.

3-Amino-4-nitro-2-naphthoic acid (CAS 498546-32-0) is a high-purity analytical reference standard with the molecular formula C11H8N2O4 and a molecular weight of 232.19 g/mol.

3-Amino-4-nitro-2-naphthoic acid (C11H8N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
