Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(2,4-Dichlorophenyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole (CAS 400077-13-6), molecular formula C12H10Cl2N2 and molecular weight 253.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(2,4-Dichlorophenyl)-1,4,5,6-tetrahydrocyclopenta[c]pyrazole (C12H10Cl2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
