4-amino-2-cyclohexyl-1,5-dimethyl-2,3-dihydro-1H-pyrazol-3-one dihydrochloride CAS 1955498-10-8

Description

The occurrence of 4-amino-2-cyclohexyl-1,5-dimethyl-2,3-dihydro-1H-pyrazol-3-one dihydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-amino-2-cyclohexyl-1,5-dimethyl-2,3-dihydro-1H-pyrazol-3-one dihydrochloride (CAS 1955498-10-8), a certified reference material (molecular formula C11H19N3OHCl, MW 245.75 g/mol) for analytical method development and quality control.

The molecular framework of 4-amino-2-cyclohexyl-1,5-dimethyl-2,3-dihydro-1H-pyrazol-3-one dihydrochloride (C11H19N3OHCl) is characterized by an amide group, a hydroxyl group, an ether linkage, 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.
