Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, (3AR,5R,6S,6aR)-2,2-dimethyl-5-((trityloxy)methyl)tetrahydrofuro[2,3-d][1,3]dioxol-6-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (3AR,5R,6S,6aR)-2,2-dimethyl-5-((trityloxy)methyl)tetrahydrofuro[2,3-d][1,3]dioxol-6-ol (CAS 20590-53-8), a certified reference material (molecular formula C27H28O5, MW 432.51 g/mol) for analytical method development and quality control.
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.
