Chemical Structure
Description
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.
1,2-Cyclopentanediol, 1,2-diacetate, (1R,2R)-rel- (CAS 26620-22-4), molecular formula C23H22F3N3O and molecular weight 413.44 g/mol, is a CATO reference standard with documented purity and traceability.
1,2-Cyclopentanediol, 1,2-diacetate, (1R,2R)-rel- (C23H22F3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
