Chemical Structure
Description
As a certified reference material (CRM), rel-(3aR,5R,7aS)-2,3,3a,4,5,6,7,7a-Octahydro-1H-isoindol-5-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
rel-(3aR,5R,7aS)-2,3,3a,4,5,6,7,7a-Octahydro-1H-isoindol-5-ol (CAS 52865-09-5) is a high-purity analytical reference standard with the molecular formula C8H15NO and a molecular weight of 141.21 g/mol.
The molecular framework of rel-(3aR,5R,7aS)-2,3,3a,4,5,6,7,7a-Octahydro-1H-isoindol-5-ol (C8H15NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
