Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-(4,5-dihydro-4,4-dimethyl-2-oxazolyl)- CAS 950596-41-5

Description

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.

Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-(4,5-dihydro-4,4-dimethyl-2-oxazolyl)- (CAS 950596-41-5), molecular formula C28H29N3O2 and molecular weight 439.55 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Pyridine, 2,2′-[(4S,5S)-2,2-dimethyl-1,3-dioxolane-4,5-diyl]bis[6-(4,5-dihydro-4,4-dimethyl-2-oxazolyl)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.55 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).

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.
