Chemical Structure
Description
The occurrence of Ethyl 4-chloro-8-iodo-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 4-chloro-8-iodo-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylate (CAS 2365243-37-2), molecular formula C9H8ClIN4O2 and molecular weight 366.54 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 4-chloro-8-iodo-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylate (C9H8ClIN4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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 366.54 g/mol, it falls into the moderately-high-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.
As a certified reference material (CRM), Ethyl 4-chloro-8-iodo-7-methylpyrazolo[1,5-a][1,3,5]triazine-2-carboxylate 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.
