Chemical Structure

4-Ethyl-4'-(trans-4-propylcyclohexyl)biphenyl CAS 84540-37-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Ethyl-4'-(trans-4-propylcyclohexyl)biphenyl.

4-Ethyl-4'-(trans-4-propylcyclohexyl)biphenyl (CAS 84540-37-4) is a high-purity analytical reference standard with the molecular formula C23H30 and a molecular weight of 306.48 g/mol.

Based on its molecular formula C23H30, 4-Ethyl-4'-(trans-4-propylcyclohexyl)biphenyl contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
