The occurrence of Etofenprox-(<I>ethoxy</I>-d<SUB>5</SUB>) is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Etofenprox-(<I>ethoxy</I>-d<SUB>5</SUB>) (CAS 1705649-55-3), a certified reference material (molecular formula C25H23D5O3, MW 381.52 g/mol) for analytical method development and quality control.
Structurally, Etofenprox-(<I>ethoxy</I>-d<SUB>5</SUB>) (C25H23D5O3) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 381.52 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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 Etofenprox-(<I>ethoxy</I>-d<SUB>5</SUB>) 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.
