Chemical Structure

Cyclopenta[cd]pyren-4(3H)-one CAS 73473-56-0 chemical structure

Description

Structurally, Cyclopenta[cd]pyren-4(3H)-one (C18H10O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 242.27 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.

Cyclopenta[cd]pyren-4(3H)-one (CAS 73473-56-0) is a high-purity analytical reference standard with the molecular formula C18H10O and a molecular weight of 242.27 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Cyclopenta[cd]pyren-4(3H)-one 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.
