Chemical Structure

3,3-dimethoxy-2,2,4,4-tetramethylcyclobutan-1-ol CAS 1936554-46-9 chemical structure

Description

3,3-dimethoxy-2,2,4,4-tetramethylcyclobutan-1-ol (CAS 1936554-46-9) is a high-purity analytical reference standard with the molecular formula C10H20O3 and a molecular weight of 188.26 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3,3-dimethoxy-2,2,4,4-tetramethylcyclobutan-1-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
