methyl 3-(chlorosulfonyl)-2-phenylpropanoate CAS 1803560-95-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 3-(chlorosulfonyl)-2-phenylpropanoate.

methyl 3-(chlorosulfonyl)-2-phenylpropanoate (CAS 1803560-95-3) is a high-purity analytical reference standard with the molecular formula C10H11ClO4S and a molecular weight of 262.71 g/mol.

methyl 3-(chlorosulfonyl)-2-phenylpropanoate (C10H11ClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
