Chemical Structure

Ethyl 4-pentylbenzoate CAS 475208-89-0 chemical structure

Description

Ethyl 4-pentylbenzoate (CAS 475208-89-0), molecular formula C14H20O2 and molecular weight 220.31 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 4-pentylbenzoate (C14H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 220.31 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.

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.
