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.

702681-67-2 999KY5ZIGB CP-868388 UNII-999KY5ZIGB 1-Piperidinecarboxylic acid, 3-(3-(1-carboxy-1-methylethoxy)phenyl)-, 1-((4-(1-methylethyl)phenyl)methyl) ester, (3S)- S)-3-(3-(1-carboxy-1-methylethoxy)phenyl)piperidine-1-carboxylic acid 4-isopropylbenzyl ester (-)-CP-868388 (CAS 702681-67-2) is a high-purity analytical reference standard with the molecular formula C26H45NO5 and a molecular weight of 451.64 g/mol.

702681-67-2 999KY5ZIGB CP-868388 UNII-999KY5ZIGB 1-Piperidinecarboxylic acid, 3-(3-(1-carboxy-1-methylethoxy)phenyl)-, 1-((4-(1-methylethyl)phenyl)methyl) ester, (3S)- S)-3-(3-(1-carboxy-1-methylethoxy)phenyl)piperidine-1-carboxylic acid 4-isopropylbenzyl ester (-)-CP-868388 (C26H45NO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).

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.
