The occurrence of 3,5-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (CAS 898757-11-4), a certified reference material (molecular formula C17H22Cl2O3, MW 345.26 g/mol) for analytical method development and quality control.
3,5-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (C17H22Cl2O3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 3,5-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone 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.
