Chemical Structure
Description
The occurrence of 4-(4-Pentylbenzoyl)phenyl acetate is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(4-Pentylbenzoyl)phenyl acetate (CAS 890099-76-0) is a high-purity analytical reference standard with the molecular formula C20H22O3 and a molecular weight of 310.39 g/mol.
Structurally, 4-(4-Pentylbenzoyl)phenyl acetate (C20H22O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 310.39 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(4-Pentylbenzoyl)phenyl acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
