Chemical Structure
Description
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.
CATO supplies (4R,5R)-4,5-Dihydro-5-[4-(methylsulfonyl)phenyl]-2-phenyl-4-oxazolemethanol-d3 (CAS 1246814-83-4), a certified reference material (molecular formula C17H14D3NO4S, MW 334.40 g/mol) for analytical method development and quality control.
Structurally, (4R,5R)-4,5-Dihydro-5-[4-(methylsulfonyl)phenyl]-2-phenyl-4-oxazolemethanol-d3 (C17H14D3NO4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 334.40 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
