Chemical Structure
Description
1-(4-(Chloromethyl)pyridin-2-yl)-4-methylpiperazine (CAS 1251350-16-9), molecular formula C11H16ClN3 and molecular weight 225.72 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-(Chloromethyl)pyridin-2-yl)-4-methylpiperazine (C11H16ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(4-(Chloromethyl)pyridin-2-yl)-4-methylpiperazine 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.
