Chemical Structure

(R)-3-(tert-Butyldimethylsilyloxy)-4-chlorobutanal CAS 119136-98-0 chemical structure

Description

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.

(R)-3-(tert-Butyldimethylsilyloxy)-4-chlorobutanal (CAS 119136-98-0) is a high-purity analytical reference standard with the molecular formula C10H21ClO2Si and a molecular weight of 236.81 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (R)-3-(tert-Butyldimethylsilyloxy)-4-chlorobutanal is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.81 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.

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