Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.50 g/mol gives 2-(4-Bromo-1h-pyrazol-1-yl)ethan-1-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-Bromo-1h-pyrazol-1-yl)ethan-1-amine hydrochloride (CAS 663941-75-1), molecular formula C5H8BrN3HCl and molecular weight 226.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Bromo-1h-pyrazol-1-yl)ethan-1-amine hydrochloride (C5H8BrN3HCl) is characterized by a nitrile group, chlorine/bromine substitution. 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. 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.
As a certified reference material (CRM), 2-(4-Bromo-1h-pyrazol-1-yl)ethan-1-amine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
