Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 614.98 g/mol gives Dihexadecyl Phthalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dihexadecyl Phthalate (CAS 13372-18-4), a certified reference material (molecular formula C40H70O4, MW 614.98 g/mol) for analytical method development and quality control.
The molecular framework of Dihexadecyl Phthalate (C40H70O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Dihexadecyl 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.
