Chemical Structure
Description
N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (CAS 499103-68-3), molecular formula C20H19N3O4S3 and molecular weight 461.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((5-((4-methoxybenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)acetamide (C20H19N3O4S3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 461.58 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
