N1-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-N2,N2-dimethylethane-1,2-diamine hydrochloride CAS 1856048-10-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N1-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-N2,N2-dimethylethane-1,2-diamine hydrochloride.

N1-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-N2,N2-dimethylethane-1,2-diamine hydrochloride (CAS 1856048-10-6), molecular formula C10H19FN4HCl and molecular weight 250.75 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N1-((5-Fluoro-1,3-dimethyl-1H-pyrazol-4-yl)methyl)-N2,N2-dimethylethane-1,2-diamine hydrochloride (C10H19FN4HCl) is characterized by a nitrile group, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
