Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-2-(hydroxymethyl)pyrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 3-Chloro-2-(hydroxymethyl)pyrazine (CAS 89283-32-9), a certified reference material (molecular formula C5H5ClN2O, MW 144.56 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
