Chemical Structure
Description
Methyl 3-amino-4-methyl-5-nitrobenzoate (CAS 72922-60-2) is a high-purity analytical reference standard with the molecular formula C9H10N2O4 and a molecular weight of 210.19 g/mol.
Structurally, Methyl 3-amino-4-methyl-5-nitrobenzoate (C9H10N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 210.19 g/mol, it falls into the medium-molecular-weight range. 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).
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.
CATO manufactures Methyl 3-amino-4-methyl-5-nitrobenzoate 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.
