As a certified reference material (CRM), Tert-butyl (R)-(1-hydroxy-5-(methylthio)pentan-3-yl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Tert-butyl (R)-(1-hydroxy-5-(methylthio)pentan-3-yl)carbamate (CAS 173472-43-0), molecular formula C11H23NO3S and molecular weight 249.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H23NO3S, Tert-butyl (R)-(1-hydroxy-5-(methylthio)pentan-3-yl)carbamate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 249.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
