Chemical Structure
Description
The occurrence of tert-Butyl (R)-2-cyclopentylpiperazine-1-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies tert-Butyl (R)-2-cyclopentylpiperazine-1-carboxylate (CAS 1240588-63-9), a certified reference material (molecular formula C14H26N2O2, MW 254.37 g/mol) for analytical method development and quality control.
tert-Butyl (R)-2-cyclopentylpiperazine-1-carboxylate (C14H26N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
