Chemical Structure
Description
Ethyl 7-(2-chlorophenyl)pyrazolo[1,5-a]pyrimidine-6-carboxylate (CAS 60868-62-4), molecular formula C15H12ClN3O2 and molecular weight 301.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 7-(2-chlorophenyl)pyrazolo[1,5-a]pyrimidine-6-carboxylate (C15H12ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 301.73 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
