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 38275-42-2 5-Chloro-2-methylsulfanyl-pyrimidine MFCD00489773 (CAS 38275-42-2), a certified reference material (molecular formula C5H11ClN2S, MW 166.67 g/mol) for analytical method development and quality control.
The molecular framework of 38275-42-2 5-Chloro-2-methylsulfanyl-pyrimidine MFCD00489773 (C5H11ClN2S) is characterized by sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
