Chemical Structure
Description
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.
CATO supplies 4-Bromo-2-(methylthio)pyrimidine (CAS 959236-97-6), a certified reference material (molecular formula C5H5BrN2S, MW 205.08 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-2-(methylthio)pyrimidine (C5H5BrN2S) contains a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 205.08 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
