Chemical Structure
Description
CATO supplies 2,2-[(1-methylethylidene)bis(cyclohexane-4,1-diyloxymethylene)]bisoxirane (CAS 13410-58-7), a certified reference material (molecular formula C21H36O4, MW 352.51 g/mol) for analytical method development and quality control.
Structurally, 2,2-[(1-methylethylidene)bis(cyclohexane-4,1-diyloxymethylene)]bisoxirane (C21H36O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 352.51 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
