Chemical Structure
Description
rel-(1R,2S)-1-((tert-Butoxycarbonyl)amino)-2-vinylcyclopropanecarboxylic acid (CAS 213316-50-8) is a high-purity analytical reference standard with the molecular formula C11H17NO4 and a molecular weight of 227.26 g/mol.
rel-(1R,2S)-1-((tert-Butoxycarbonyl)amino)-2-vinylcyclopropanecarboxylic acid (C11H17NO4) contains an amino-acid-derived structure, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
