Chemical Structure
Description
tert-Butyl 3-hydroxy-2,2-dimethylpropanoate (CAS 25307-76-0), molecular formula C9H18O3 and molecular weight 174.24 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 3-hydroxy-2,2-dimethylpropanoate (C9H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
