Chemical Structure
Description
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.
951886-81-0 Ethyl 8-(5-Chloro-2-methoxyphenyl)-8-oxooctanoate MFCD09801933 (CAS 951886-81-0), molecular formula C17H23ClO4 and molecular weight 326.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 951886-81-0 Ethyl 8-(5-Chloro-2-methoxyphenyl)-8-oxooctanoate MFCD09801933 (C17H23ClO4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 951886-81-0 Ethyl 8-(5-Chloro-2-methoxyphenyl)-8-oxooctanoate MFCD09801933 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.
