Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.30 g/mol gives 2,4-Bis(methylsulfonyl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Bis(methylsulfonyl)benzaldehyde (CAS 1845690-57-4), molecular formula C9H10O5S2 and molecular weight 262.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Bis(methylsulfonyl)benzaldehyde (C9H10O5S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
