Chemical Structure

N-hydroxy-4-((2-methoxyethyl)amino)-1,2,5-oxadiazole-3-carbimidoyl chloride CAS 1204669-61-3 chemical structure

Description

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, N-hydroxy-4-((2-methoxyethyl)amino)-1,2,5-oxadiazole-3-carbimidoyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 220.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

N-hydroxy-4-((2-methoxyethyl)amino)-1,2,5-oxadiazole-3-carbimidoyl chloride (CAS 1204669-61-3), molecular formula C6H9ClN4O3 and molecular weight 220.61 g/mol, is a CATO reference standard with documented purity and traceability.

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), N-hydroxy-4-((2-methoxyethyl)amino)-1,2,5-oxadiazole-3-carbimidoyl chloride 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.
