Chemical Structure

4,4-Dimethoxy-2-methylbutan-2-ol CAS 31525-67-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 148.20 g/mol gives 4,4-Dimethoxy-2-methylbutan-2-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4-Dimethoxy-2-methylbutan-2-ol (CAS 31525-67-4), molecular formula C7H16O3 and molecular weight 148.20 g/mol, is a CATO reference standard with documented purity and traceability.

4,4-Dimethoxy-2-methylbutan-2-ol (C7H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
