2-Hydroxy-5-methoxy-3-nitro-benzaldehyde 2-hydroxy-3-nitro-5-methoxybenzaldehyde 2-hydroxy-5-methoxy-3-nitrobenzaldehyde 3-nitro-5-methoxysalicylaldehyde 34549-69-4 5-methoxy-3-nitrosalicylaldehyde (C8H13NO5) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
