Description

Compared with other compounds in its class, the molecular weight of 331.19 g/mol gives tert-butyl N-(6-bromothiazolo[4,5-b]pyrazin-2-yl)carbamate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-butyl N-(6-bromothiazolo[4,5-b]pyrazin-2-yl)carbamate (CAS 2680840-90-6), molecular formula C10H11BrN4O2S and molecular weight 331.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of tert-butyl N-(6-bromothiazolo[4,5-b]pyrazin-2-yl)carbamate (C10H11BrN4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
