Chemical Structure
Description
(S)-2-(4-Chlorophenyl)-3,3-dimethyl-N-(5-phenylthiazol-2-yl)butanamide (CAS 1208552-99-1) is a high-purity analytical reference standard with the molecular formula C21H21ClN2OS and a molecular weight of 384.92 g/mol.
Structurally, (S)-2-(4-Chlorophenyl)-3,3-dimethyl-N-(5-phenylthiazol-2-yl)butanamide (C21H21ClN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 384.92 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).
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.
