Chemical Structure
Description
4-(4-Bromophenyl)-2-hydrazinyl-5-methylthiazole (CAS 886494-27-5), molecular formula C10H10BrN3S and molecular weight 284.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(4-Bromophenyl)-2-hydrazinyl-5-methylthiazole (C10H10BrN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 284.18 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.
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.
