Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Chloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (CAS 898785-94-9) is a high-purity analytical reference standard with the molecular formula C17H23ClO3 and a molecular weight of 310.82 g/mol.
The molecular framework of 3-Chloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (C17H23ClO3) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3-Chloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
