3-Amino-4-hydroxyphenylarsonic acid CAS 2163-77-1

Description

The occurrence of 3-Amino-4-hydroxyphenylarsonic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Amino-4-hydroxyphenylarsonic acid (CAS 2163-77-1), molecular formula C6H8AsNO4 and molecular weight 233.05 g/mol, is a CATO reference standard with documented purity and traceability.

3-Amino-4-hydroxyphenylarsonic acid (C6H8AsNO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 3-Amino-4-hydroxyphenylarsonic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
