3-Amino-3-tert-butyl-1-[2-chloro-5-(trifluoromethyl)phenyl]thiourea CAS 721415-49-2

Description

3-Amino-3-tert-butyl-1-[2-chloro-5-(trifluoromethyl)phenyl]thiourea (CAS 721415-49-2), molecular formula C12H15ClF3N3S and molecular weight 325.78 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Amino-3-tert-butyl-1-[2-chloro-5-(trifluoromethyl)phenyl]thiourea (C12H15ClF3N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 325.78 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.
