Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.80 g/mol gives Chloropyramine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chloropyramine (CAS 59-32-5), a certified reference material (molecular formula C16H20ClN3, MW 289.80 g/mol) for analytical method development and quality control.
The molecular framework of Chloropyramine (C16H20ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
