Chemical Structure

Paliperidone USP Related Compound A CAS 849903-79-3 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 Paliperidone USP Related Compound A.

CATO supplies Paliperidone USP Related Compound A (CAS 849903-79-3), a pharmacopoeial impurity reference standard (molecular formula C11H16N2O2, MW 208.26 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Paliperidone USP Related Compound A (C11H16N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Paliperidone USP Related Compound A 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.
