Chemical Structure
Description
As a certified reference material (CRM), N-(6-Chloro-9H-purin-2-yl)acetamide 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.
N-(6-Chloro-9H-purin-2-yl)acetamide (CAS 7602-01-9), molecular formula C7H6ClN5O and molecular weight 211.61 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N-(6-Chloro-9H-purin-2-yl)acetamide (C7H6ClN5O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 211.61 g/mol, it falls into the medium-molecular-weight range. 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).
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.
