Chemical Structure
Description
Dimethylisopropylsilane (CAS 18209-61-5), molecular formula C5H14Si and molecular weight 102.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dimethylisopropylsilane (C5H14Si) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
