Chemical Structure
Description
The occurrence of 4-Cyclopropyl-1-methyl-1H-indazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Cyclopropyl-1-methyl-1H-indazole (CAS 1521881-14-0), a certified reference material (molecular formula C11H12N2, MW 172.23 g/mol) for analytical method development and quality control.
4-Cyclopropyl-1-methyl-1H-indazole (C11H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
