Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Bromo-8-methylthioimidazo[1,2-a]pyrazinamine.
6-Bromo-8-methylthioimidazo[1,2-a]pyrazinamine (CAS 887475-71-0), molecular formula C7H6BrN3S and molecular weight 244.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-8-methylthioimidazo[1,2-a]pyrazinamine (C7H6BrN3S) is characterized by a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
