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.
2-(Benzo[d]oxazol-2-ylthio)-N-(4-(p-tolyl)thiazol-2-yl)acetamide (CAS 79420-04-5) is a high-purity analytical reference standard with the molecular formula C19H15N3O2S2 and a molecular weight of 381.47 g/mol.
Structurally, 2-(Benzo[d]oxazol-2-ylthio)-N-(4-(p-tolyl)thiazol-2-yl)acetamide (C19H15N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 381.47 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.
