Methyl 2-(chlorosulfonyl)-5-methoxybenzoate CAS 65397-56-0

Description

Compared with other compounds in its class, the molecular weight of 264.68 g/mol gives Methyl 2-(chlorosulfonyl)-5-methoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 2-(chlorosulfonyl)-5-methoxybenzoate (CAS 65397-56-0) is a high-purity analytical reference standard with the molecular formula C9H9ClO5S and a molecular weight of 264.68 g/mol.

The molecular framework of Methyl 2-(chlorosulfonyl)-5-methoxybenzoate (C9H9ClO5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
