Chemical Structure

Methyl 3-((tert-Butyldimethylsilyl)oxy)-2,2-dimethylpropanoate CAS 361547-56-0 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 3-((tert-Butyldimethylsilyl)oxy)-2,2-dimethylpropanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.42 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.

Methyl 3-((tert-Butyldimethylsilyl)oxy)-2,2-dimethylpropanoate (CAS 361547-56-0) is a high-purity analytical reference standard with the molecular formula C12H26O3Si and a molecular weight of 246.42 g/mol.

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.
