Chemical Structure

Methyl 5-(chlorosulfonyl)-2,3-dihydro-1H-indene-2-carboxylate CAS 600166-73-2 chemical structure

Description

The occurrence of Methyl 5-(chlorosulfonyl)-2,3-dihydro-1H-indene-2-carboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Methyl 5-(chlorosulfonyl)-2,3-dihydro-1H-indene-2-carboxylate (CAS 600166-73-2), a certified reference material (molecular formula C11H11ClO4S, MW 274.72 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Methyl 5-(chlorosulfonyl)-2,3-dihydro-1H-indene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.72 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.
