Description

As a certified reference material (CRM), (1R,2R,3aS,9aS)-2-((Tetrahydro-2H-pyran-2-yl)oxy)-1-((3S,E)-3-((tetrahydro-2H-pyran-2-yl)oxy)oct-1-en-1-yl)-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]naphthalen-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.

CATO supplies (1R,2R,3aS,9aS)-2-((Tetrahydro-2H-pyran-2-yl)oxy)-1-((3S,E)-3-((tetrahydro-2H-pyran-2-yl)oxy)oct-1-en-1-yl)-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]naphthalen-5-ol (CAS 81846-28-8), a certified reference material (molecular formula C31H46O5, MW 498.69 g/mol) for analytical method development and quality control.

Based on its molecular formula C31H46O5, (1R,2R,3aS,9aS)-2-((Tetrahydro-2H-pyran-2-yl)oxy)-1-((3S,E)-3-((tetrahydro-2H-pyran-2-yl)oxy)oct-1-en-1-yl)-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]naphthalen-5-ol contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 498.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
