Chemical Structure
Description
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.
CATO supplies 186205-15-2 6-chloro-[1,2,5]oxadiazolo[3,4-b]pyrazin-5-amine (CAS 186205-15-2), a certified reference material (molecular formula C4H2ClN5O, MW 171.54 g/mol) for analytical method development and quality control.
The molecular framework of 186205-15-2 6-chloro-[1,2,5]oxadiazolo[3,4-b]pyrazin-5-amine (C4H2ClN5O) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 186205-15-2 6-chloro-[1,2,5]oxadiazolo[3,4-b]pyrazin-5-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
