Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 189.69 g/mol gives (3-(Tert-butyl)-1h-pyrazol-5-yl)methanamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3-(Tert-butyl)-1h-pyrazol-5-yl)methanamine hydrochloride (CAS 1028458-52-7) is a high-purity analytical reference standard with the molecular formula C8H15N3HCl and a molecular weight of 189.69 g/mol.
Structurally, (3-(Tert-butyl)-1h-pyrazol-5-yl)methanamine hydrochloride (C8H15N3HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 189.69 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
