Chemical Structure
Description
The occurrence of 2-Nitrophenylarsonic Acid is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Nitrophenylarsonic Acid (CAS 5410-29-7), a certified reference material (molecular formula C6H6AsNO5, MW 247.04 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6AsNO5, 2-Nitrophenylarsonic Acid contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Nitrophenylarsonic 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.
