Chemical Structure

Dicyclopentadiene dioxide CAS 81-21-0 chemical structure

Description

Dicyclopentadiene dioxide (CAS 81-21-0) is a high-purity analytical reference standard with the molecular formula C27H48 and a molecular weight of 372.67 g/mol.

Structurally, Dicyclopentadiene dioxide (C27H48) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 372.67 g/mol, it falls into the moderately-high-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.

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.

CATO manufactures Dicyclopentadiene dioxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
