Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone.
2,6-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (CAS 898757-01-2), molecular formula C17H22Cl2O3 and molecular weight 345.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichloro-5-(5,5-dimethyl-1,3-dioxan-2-yl)valerophenone (C17H22Cl2O3) 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. 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.
As a certified reference material (CRM), 2,6-Dichloro-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.
