Chemical Structure
Description
Structurally, 24864-19-5 NSC-122283 NSC122283 Thiazole, 4-(4-biphenylyl)-2-methyl- Thiazole,1'-biphenyl]-4-yl-2-methyl- (C16H29NS) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 267.47 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
24864-19-5 NSC-122283 NSC122283 Thiazole, 4-(4-biphenylyl)-2-methyl- Thiazole,1'-biphenyl]-4-yl-2-methyl- (CAS 24864-19-5), molecular formula C16H29NS and molecular weight 267.47 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
