1-(4-carboxyphenyl) piperazine 4-(1-piperazinyl)-benzoic acid 4-(1-piperazinyl)benzoic acid 4-(Piperazin-1-yl)-benzoic acid 4-(piperazin-1-yl)benzoic acid 4-piperazin-1-yl-benzoic acid 4-piperazin-1-ylbenzoic acid 85474-75-5 (CAS 85474-75-5), molecular formula C11H14N2O2 and molecular weight 206.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(4-carboxyphenyl) piperazine 4-(1-piperazinyl)-benzoic acid 4-(1-piperazinyl)benzoic acid 4-(Piperazin-1-yl)-benzoic acid 4-(piperazin-1-yl)benzoic acid 4-piperazin-1-yl-benzoic acid 4-piperazin-1-ylbenzoic acid 85474-75-5 (C11H14N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 1-(4-carboxyphenyl) piperazine 4-(1-piperazinyl)-benzoic acid 4-(1-piperazinyl)benzoic acid 4-(Piperazin-1-yl)-benzoic acid 4-(piperazin-1-yl)benzoic acid 4-piperazin-1-yl-benzoic acid 4-piperazin-1-ylbenzoic acid 85474-75-5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
