84131-91-9 Butanoic acid,2-methyl-, 1,1'-anhydride, (2S,2'S)- CTK5F1861 CAS 84131-91-9

Description

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.

84131-91-9 Butanoic acid,2-methyl-, 1,1'-anhydride, (2S,2'S)- CTK5F1861 (CAS 84131-91-9), molecular formula C10H18O3 and molecular weight 186.25 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H18O3, 84131-91-9 Butanoic acid,2-methyl-, 1,1'-anhydride, (2S,2'S)- CTK5F1861 contains 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 186.25 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.

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.
