Chemical Structure

Cytarabine Impurity N3 CAS 30902-36-4 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 Cytarabine Impurity N3.

As a process- or degradation-related impurity, Cytarabine Impurity N3 (CAS 30902-36-4, C9H13N3O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Cytarabine Impurity N3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.22 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), Cytarabine Impurity N3 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.
