Chemical Structure

Reserpine Impurity 9 CAS 1446557-12-5 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 Reserpine Impurity 9.

CATO supplies Reserpine Impurity 9 (CAS 1446557-12-5), a pharmacopoeial impurity reference standard (molecular formula C33H40N2O10, MW 624.68 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Reserpine Impurity 9 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 624.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Reserpine Impurity 9 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.
