Compared with other compounds in its class, the molecular weight of 428.52 g/mol gives (3aS,4S,6aR)-2,2-Dimethyl-6-((trityloxy)methyl)-4,6a-dihydro-3aH-cyclopenta[d][1,3]dioxol-4-ol, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3aS,4S,6aR)-2,2-Dimethyl-6-((trityloxy)methyl)-4,6a-dihydro-3aH-cyclopenta[d][1,3]dioxol-4-ol, 97% (CAS 163226-45-7) is a high-purity analytical reference standard with the molecular formula C28H28O4 and a molecular weight of 428.52 g/mol.
The molecular framework of (3aS,4S,6aR)-2,2-Dimethyl-6-((trityloxy)methyl)-4,6a-dihydro-3aH-cyclopenta[d][1,3]dioxol-4-ol, 97% (C28H28O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
