Chemical Structure

2-ethynylpiperazine;dihydrochloride CAS 2306276-99-1 chemical structure

Description

The molecular framework of 2-ethynylpiperazine;dihydrochloride (C6H10N2HCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2-ethynylpiperazine;dihydrochloride (CAS 2306276-99-1), molecular formula C6H10N2HCl and molecular weight 146.62 g/mol, is a CATO reference standard with documented purity and traceability.

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.
