Chemical Structure

(2E,5E)-2,5-Bis[(4-chlorophenyl)methylene]cyclopentanone CAS 106115-45-1 chemical structure

Description

The occurrence of (2E,5E)-2,5-Bis[(4-chlorophenyl)methylene]cyclopentanone is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E,5E)-2,5-Bis[(4-chlorophenyl)methylene]cyclopentanone (CAS 106115-45-1), a certified reference material (molecular formula C19H14Cl2O, MW 329.22 g/mol) for analytical method development and quality control.

Structurally, (2E,5E)-2,5-Bis[(4-chlorophenyl)methylene]cyclopentanone (C19H14Cl2O) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 329.22 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
