Chemical Structure
Description
Cyclopentanecarboxylic acid, 2-hydroxy-, ethyl ester, (1R,2R)-rel- (C8H14O3) 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.
Cyclopentanecarboxylic acid, 2-hydroxy-, ethyl ester, (1R,2R)-rel- (CAS 1883-91-6), molecular formula C8H14O3 and molecular weight 158.19 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
