As a certified reference material (CRM), 1-(2-chlorobenzyl)-3,5-dimethyl-N-(thien-2-ylmethyl)-1H-pyrazol-4-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.
1-(2-chlorobenzyl)-3,5-dimethyl-N-(thien-2-ylmethyl)-1H-pyrazol-4-amine (CAS 1172746-62-1), molecular formula C17H18ClN3S and molecular weight 331.86 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-(2-chlorobenzyl)-3,5-dimethyl-N-(thien-2-ylmethyl)-1H-pyrazol-4-amine (C17H18ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 331.86 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
