(1R,3r)-3-((tert-butyldimethylsilyl)oxy)cyclobutane-1-carboxylic acid CAS 1431285-79-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 230.38 g/mol gives (1R,3r)-3-((tert-butyldimethylsilyl)oxy)cyclobutane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1R,3r)-3-((tert-butyldimethylsilyl)oxy)cyclobutane-1-carboxylic acid (CAS 1431285-79-8) is a high-purity analytical reference standard with the molecular formula C11H22O3Si and a molecular weight of 230.38 g/mol.

Structurally, (1R,3r)-3-((tert-butyldimethylsilyl)oxy)cyclobutane-1-carboxylic acid (C11H22O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 230.38 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
