[S-(E)]-3-[[[(2-Carboxyethyl)thio][3-[2-(7-chloro-2-quinolinyl)ethenyl]phenyl]methyl]thio]propanoic Acid 1-Methyl Ester CAS 120385-98-0 chemical structure

Description

The occurrence of [S-(E)]-3-[[[(2-Carboxyethyl)thio][3-[2-(7-chloro-2-quinolinyl)ethenyl]phenyl]methyl]thio]propanoic Acid 1-Methyl Ester is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies [S-(E)]-3-[[[(2-Carboxyethyl)thio][3-[2-(7-chloro-2-quinolinyl)ethenyl]phenyl]methyl]thio]propanoic Acid 1-Methyl Ester (CAS 120385-98-0), a certified reference material (molecular formula C25H24ClNO4S2, MW 502.05 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, [S-(E)]-3-[[[(2-Carboxyethyl)thio][3-[2-(7-chloro-2-quinolinyl)ethenyl]phenyl]methyl]thio]propanoic Acid 1-Methyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 502.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), [S-(E)]-3-[[[(2-Carboxyethyl)thio][3-[2-(7-chloro-2-quinolinyl)ethenyl]phenyl]methyl]thio]propanoic Acid 1-Methyl Ester 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.
