Chemical Structure

Rel-1-((1s,4r)-4-butylcyclohexyl)-4-ethoxybenzene CAS 84540-34-1 chemical structure

Description

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.

CATO supplies Rel-1-((1s,4r)-4-butylcyclohexyl)-4-ethoxybenzene (CAS 84540-34-1), a certified reference material (molecular formula C18H28O, MW 260.41 g/mol) for analytical method development and quality control.

Structurally, Rel-1-((1s,4r)-4-butylcyclohexyl)-4-ethoxybenzene (C18H28O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.41 g/mol, it falls into the medium-molecular-weight range. 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.
