Chemical Structure
Description
(S)-2-(2,4-Dichlorobenzyl)piperazine (CAS 1240586-49-5) is a high-purity analytical reference standard with the molecular formula C11H14Cl2N2 and a molecular weight of 245.15 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, (S)-2-(2,4-Dichlorobenzyl)piperazine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 245.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
