Chemical Structure
Description
D-Proline, 2-(2-pyridinylmethyl)-, hydrochloride (1:2) (CAS 1217860-92-8), molecular formula C11H14N2O2HCl and molecular weight 242.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of D-Proline, 2-(2-pyridinylmethyl)-, hydrochloride (1:2) (C11H14N2O2HCl) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 D-Proline, 2-(2-pyridinylmethyl)-, hydrochloride (1:2) 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.
