Chemical Structure

1-ethynyl-1,1'-bi(cyclopropane) CAS 1391837-72-1 chemical structure

Description

The occurrence of 1-ethynyl-1,1'-bi(cyclopropane) is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-ethynyl-1,1'-bi(cyclopropane) (CAS 1391837-72-1) is a high-purity analytical reference standard with the molecular formula C8H10 and a molecular weight of 106.17 g/mol.

The molecular framework of 1-ethynyl-1,1'-bi(cyclopropane) (C8H10) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
