Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 3-hydroxy-5-nitrobenzoate (CAS 55076-32-9) is a high-purity analytical reference standard with the molecular formula C8H7NO5 and a molecular weight of 197.14 g/mol.
The molecular framework of Methyl 3-hydroxy-5-nitrobenzoate (C8H7NO5) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Methyl 3-hydroxy-5-nitrobenzoate 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.
