Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Amino-2-oxoethyl)pyridin-1-ium chloride.
1-(2-Amino-2-oxoethyl)pyridin-1-ium chloride (CAS 41220-29-5) is a high-purity analytical reference standard with the molecular formula C7H9N2OCl and a molecular weight of 172.61 g/mol.
The molecular framework of 1-(2-Amino-2-oxoethyl)pyridin-1-ium chloride (C7H9N2OCl) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
As a certified reference material (CRM), 1-(2-Amino-2-oxoethyl)pyridin-1-ium chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
