2. A nitrogen-containing compound derived from lidocaine metabolism used in medical diagnostics ; an organic molecule characterized by a piperidine configuration and coloxyl substitution ; a substance measured in pharmacokinetics to assess the processing of local anesthetics
3. A metabolic product of the anesthetic lidocaine featuring piperidine and coloxyl moieties ; a chemical entity relevant in biochemical and clinical analysis of drug metabolism ; an organic compound serving as an indicator of lidocaine clearance in biological systems

Etymology: "Pipecoloxylidide" is a systematic chemical name built from two parts. "Pipecol-" comes from pipecolic acid, named for its relation to piperidine, the ring-shaped base of black pepper's alkaloids. Its root is the Latin "piper," pepper. The second part, "xylidide," comes from xylidine, an aromatic amine whose name draws on xylene, from the Greek "xylon," wood, since xylene was first obtained from wood tar. The "-ide" ending marks an amide, a compound in which a nitrogen atom is bonded to a carbonyl carbon. The name therefore reads as a structural description: pipecolic acid joined to a xylidine through an amide bond. The second element is "xylidide," not "coloxyl" as the source meaning has it. Lidocaine is itself a xylidide, which explains why this metabolite carries the same ending.
