2-(4-Ethynylphenyl)-1H-imidazole CAS 1270965-27-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Ethynylphenyl)-1H-imidazole.

2-(4-Ethynylphenyl)-1H-imidazole (CAS 1270965-27-9), molecular formula C11H8N2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(4-Ethynylphenyl)-1H-imidazole (C11H8N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 168.19 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
