7-chloro-[1,3]thiazolo[4,5-b]quinoxalin-2-amine CAS 120317-27-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-chloro-[1,3]thiazolo[4,5-b]quinoxalin-2-amine.

7-chloro-[1,3]thiazolo[4,5-b]quinoxalin-2-amine (CAS 120317-27-3) is a high-purity analytical reference standard with the molecular formula C9H5ClN4S and a molecular weight of 236.68 g/mol.

7-chloro-[1,3]thiazolo[4,5-b]quinoxalin-2-amine (C9H5ClN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 7-chloro-[1,3]thiazolo[4,5-b]quinoxalin-2-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.
