Chemical Structure
Description
The molecular framework of Methyl 4-amino-1-ethyl-1H-indazole-6-carboxylate (C11H13N3O2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Methyl 4-amino-1-ethyl-1H-indazole-6-carboxylate (CAS 706818-92-0), molecular formula C11H13N3O2 and molecular weight 219.24 g/mol, is a CATO reference standard with documented purity and traceability.
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.
