Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 304.38 g/mol gives Butyl Cyclohexyl Phthalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Butyl Cyclohexyl Phthalate (CAS 84-64-0) is a high-purity analytical reference standard with the molecular formula C18H24O4 and a molecular weight of 304.38 g/mol.
The molecular framework of Butyl Cyclohexyl Phthalate (C18H24O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Butyl Cyclohexyl Phthalate 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.
