Chemical Structure
Description
The occurrence of 8-(4-Chlorophenoxy)-2-methylene-octanoic Acid Ethyl Ester 82258-37-5 Ethyl 8-(4-Chlorophenoxy)-2-methylen-octanoate is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 8-(4-Chlorophenoxy)-2-methylene-octanoic Acid Ethyl Ester 82258-37-5 Ethyl 8-(4-Chlorophenoxy)-2-methylen-octanoate (CAS 82258-37-5), a certified reference material (molecular formula C17H23ClO3, MW 310.82 g/mol) for analytical method development and quality control.
The molecular framework of 8-(4-Chlorophenoxy)-2-methylene-octanoic Acid Ethyl Ester 82258-37-5 Ethyl 8-(4-Chlorophenoxy)-2-methylen-octanoate (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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
