Chemical Structure

1-Methyl-4-{4-methyl-5H,6H,7H-cyclopenta[d]pyrimidin-2-yl}piperazine CAS 88268-11-5 chemical structure

Description

1-Methyl-4-{4-methyl-5H,6H,7H-cyclopenta[d]pyrimidin-2-yl}piperazine (CAS 88268-11-5) is a high-purity analytical reference standard with the molecular formula C13H20N4 and a molecular weight of 232.32 g/mol.

1-Methyl-4-{4-methyl-5H,6H,7H-cyclopenta[d]pyrimidin-2-yl}piperazine (C13H20N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
