Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.70 g/mol gives 3-(Piperazin-1-yl)benzoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Piperazin-1-yl)benzoic acid hydrochloride (CAS 1998216-00-4), molecular formula C11H14N2O2HCl and molecular weight 242.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H14N2O2HCl, 3-(Piperazin-1-yl)benzoic acid hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
