Chemical Structure

3-Ethynylperylene CAS 132196-66-8 chemical structure

Description

The occurrence of 3-Ethynylperylene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Ethynylperylene (CAS 132196-66-8), molecular formula C22H12 and molecular weight 276.33 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C22H12, 3-Ethynylperylene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
