Chemical Structure

rel-N-[(1R,4R)-4-(Hydroxymethyl)-2-cyclopenten-1-yl]carbamic Acid 1,1-Dimethylethyl Ester CAS 172720-97-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rel-N-[(1R,4R)-4-(Hydroxymethyl)-2-cyclopenten-1-yl]carbamic Acid 1,1-Dimethylethyl Ester.

CATO supplies rel-N-[(1R,4R)-4-(Hydroxymethyl)-2-cyclopenten-1-yl]carbamic Acid 1,1-Dimethylethyl Ester (CAS 172720-97-7), a certified reference material (molecular formula C11H19NO3, MW 213.27 g/mol) for analytical method development and quality control.

rel-N-[(1R,4R)-4-(Hydroxymethyl)-2-cyclopenten-1-yl]carbamic Acid 1,1-Dimethylethyl Ester (C11H19NO3) contains an amino-acid-derived structure, an amide 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.
