Chemical Structure
Description
The occurrence of 4-(Dichloro(methyl)silyl)butanenitrile is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(Dichloro(methyl)silyl)butanenitrile (CAS 1190-16-5) is a high-purity analytical reference standard with the molecular formula C5H9Cl2NSi and a molecular weight of 182.12 g/mol.
Owing to chlorine substitution, 4-(Dichloro(methyl)silyl)butanenitrile is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
