Compared with other compounds in its class, the molecular weight of 246.32 g/mol gives Rac-Methyl Camphorsulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rac-Methyl Camphorsulfonate (CAS 46471-67-4), molecular formula C11H18O4S and molecular weight 246.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Rac-Methyl Camphorsulfonate (C11H18O4S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
