[2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl]amine hydrobromide CAS 663941-76-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl]amine hydrobromide.

[2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl]amine hydrobromide (CAS 663941-76-2), molecular formula C7H13N3HBr and molecular weight 220.11 g/mol, is a CATO reference standard with documented purity and traceability.

[2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl]amine hydrobromide (C7H13N3HBr) contains a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
