Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 249.74 g/mol gives 3-Phenyl-4,5,6,7-tetrahydro-1H-indazol-5-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Phenyl-4,5,6,7-tetrahydro-1H-indazol-5-amine hydrochloride (CAS 1188331-72-7) is a high-purity analytical reference standard with the molecular formula C13H15N3HCl and a molecular weight of 249.74 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3-Phenyl-4,5,6,7-tetrahydro-1H-indazol-5-amine hydrochloride is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
