Chemical Structure
Description
The occurrence of Ethyl 4,5,6,7-Tetrahydro-1H-indazole-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4,5,6,7-Tetrahydro-1H-indazole-3-carboxylate (CAS 4492-02-8) is a high-purity analytical reference standard with the molecular formula C10H14N2O2 and a molecular weight of 194.23 g/mol.
The molecular framework of Ethyl 4,5,6,7-Tetrahydro-1H-indazole-3-carboxylate (C10H14N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Ethyl 4,5,6,7-Tetrahydro-1H-indazole-3-carboxylate 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.
