Chemical Structure
Description
The occurrence of 1-(5-Chlorobenzo[d]oxazol-2-yl)piperidine-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(5-Chlorobenzo[d]oxazol-2-yl)piperidine-3-carboxylic acid (CAS 1035840-87-9) is a high-purity analytical reference standard with the molecular formula C13H13ClN2O3 and a molecular weight of 280.71 g/mol.
The molecular framework of 1-(5-Chlorobenzo[d]oxazol-2-yl)piperidine-3-carboxylic acid (C13H13ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-(5-Chlorobenzo[d]oxazol-2-yl)piperidine-3-carboxylic acid 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.
