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.
CATO supplies 951888-07-6 Ethyl 7-(2,3,4-trimethoxyphenyl)-7-oxoheptanoate MFCD09801967 (CAS 951888-07-6), a certified reference material (molecular formula C18H26O6, MW 338.40 g/mol) for analytical method development and quality control.
The molecular framework of 951888-07-6 Ethyl 7-(2,3,4-trimethoxyphenyl)-7-oxoheptanoate MFCD09801967 (C18H26O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
