Chemical Structure

methyl trans-4-methylsulfonyloxycyclohexanecarboxylate CAS 2787521-93-9 chemical structure

Description

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.

methyl trans-4-methylsulfonyloxycyclohexanecarboxylate (CAS 2787521-93-9), molecular formula C9H16O5S and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of methyl trans-4-methylsulfonyloxycyclohexanecarboxylate (C9H16O5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

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.
