Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-chloro-5-fluoro-2-(methylsulfanyl)pyrimidine (CAS 6096-45-3), a certified reference material (molecular formula C5H10ClFN2S, MW 184.66 g/mol) for analytical method development and quality control.
4-chloro-5-fluoro-2-(methylsulfanyl)pyrimidine (C5H10ClFN2S) contains sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
