Chemical Structure
Description
The occurrence of (R)-1-(6-Methylpyridazin-3-yl)ethan-1-amine hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-1-(6-Methylpyridazin-3-yl)ethan-1-amine hydrochloride (CAS 1948236-87-0), molecular formula C7H11N3HCl and molecular weight 173.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, (R)-1-(6-Methylpyridazin-3-yl)ethan-1-amine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
