Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(4-Chlorophenyl)-2,6-diphenyl-4H-1,3,5-thiadiazine (CAS 56472-10-7), molecular formula C21H15ClN2S and molecular weight 362.88 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(4-Chlorophenyl)-2,6-diphenyl-4H-1,3,5-thiadiazine (C21H15ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 362.88 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.
