Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(Pyrazin-2-yl)ethan-1-amine dihydrochloride.
1-(Pyrazin-2-yl)ethan-1-amine dihydrochloride (CAS 2137775-24-5), molecular formula C6H9N3HCl and molecular weight 159.62 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(Pyrazin-2-yl)ethan-1-amine dihydrochloride (C6H9N3HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 159.62 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
