Compared with other compounds in its class, the molecular weight of 88.15 g/mol gives 2-Methyl-2-Butanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Methyl-2-Butanol (CAS 75-85-4), molecular formula C5H12O and molecular weight 88.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, 2-Methyl-2-Butanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 88.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
