Description
(3β,5Z,7E,24R)-3-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-24-hydroxy-9,10-secochola-5,7,10(19)-triene-24-carboxylic Acid Methyl Ester (CAS 252893-56-4), molecular formula C32H54O4Si and molecular weight 530.85 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C32H54O4Si, (3β,5Z,7E,24R)-3-[[(1,1-Dimethylethyl)dimethylsilyl]oxy]-24-hydroxy-9,10-secochola-5,7,10(19)-triene-24-carboxylic Acid Methyl Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 530.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
