Chemical Structure
Description
The molecular framework of 2-Ethynyl-5,6,7,8-tetrahydroimidazo[1,2-a]pyridine (C9H10N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-Ethynyl-5,6,7,8-tetrahydroimidazo[1,2-a]pyridine (CAS 2155679-68-6) is a high-purity analytical reference standard with the molecular formula C9H10N2 and a molecular weight of 146.19 g/mol.
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.
