Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (S,4S,4'S)-2,2'-(2-(Trimethylstannyl)-1,3-phenylene)bis(4-((S)-sec-butyl)-4,5-dihydrooxazole) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 491.25 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).
(S,4S,4'S)-2,2'-(2-(Trimethylstannyl)-1,3-phenylene)bis(4-((S)-sec-butyl)-4,5-dihydrooxazole) (CAS 452085-99-3), molecular formula C23H36N2O2Sn and molecular weight 491.25 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
