(2,3,4,5,6-Pentachlorophenyl)methyl 3-ethyl-4-methanesulfonyl-2-methoxybenzoate CAS 329701-57-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 520.64 g/mol gives (2,3,4,5,6-Pentachlorophenyl)methyl 3-ethyl-4-methanesulfonyl-2-methoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (2,3,4,5,6-Pentachlorophenyl)methyl 3-ethyl-4-methanesulfonyl-2-methoxybenzoate (CAS 329701-57-7), a certified reference material (molecular formula C18H15Cl5O5S, MW 520.64 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (2,3,4,5,6-Pentachlorophenyl)methyl 3-ethyl-4-methanesulfonyl-2-methoxybenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 520.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
