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-nitrophenyl)methyl]pyridin-1-ium bromide.
CATO supplies 1-[(2-nitrophenyl)methyl]pyridin-1-ium bromide (CAS 13664-80-7), a certified reference material (molecular formula C12H11N2O2Br, MW 295.14 g/mol) for analytical method development and quality control.
The molecular framework of 1-[(2-nitrophenyl)methyl]pyridin-1-ium bromide (C12H11N2O2Br) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-[(2-nitrophenyl)methyl]pyridin-1-ium bromide 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.
