4-((tert-Butyldimethylsilyl)oxy)-4-methylpent-2-ynal CAS 157522-92-4

Description

The occurrence of 4-((tert-Butyldimethylsilyl)oxy)-4-methylpent-2-ynal is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-((tert-Butyldimethylsilyl)oxy)-4-methylpent-2-ynal (CAS 157522-92-4) is a high-purity analytical reference standard with the molecular formula C12H22O2Si and a molecular weight of 226.39 g/mol.

The molecular framework of 4-((tert-Butyldimethylsilyl)oxy)-4-methylpent-2-ynal (C12H22O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
