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.
CATO supplies rel-2-((1R,3R,4''S,5R,5'S,7R)-Dispiro[adamantane-2,3'-[1,2,4]trioxolane-5',1''-cyclohexan]-4''-yl)acetic acid (CAS 774597-74-9), a certified reference material (molecular formula C18H26O5, MW 322.40 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H26O5, rel-2-((1R,3R,4''S,5R,5'S,7R)-Dispiro[adamantane-2,3'-[1,2,4]trioxolane-5',1''-cyclohexan]-4''-yl)acetic acid contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 322.40 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).
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.
