Chemical Structure
Description
The occurrence of Butyl octyl phthalate 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.
CATO supplies Butyl octyl phthalate (CAS 84-78-6), a certified reference material (molecular formula C20H30O4, MW 334.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H30O4, Butyl octyl phthalate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 334.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 octyl 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.
