Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 255.23 g/mol gives Acyclovir EP Impurity Q distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Acyclovir EP Impurity Q (CAS CATO-C4X-101017), a pharmacopoeial impurity reference standard (molecular formula C9H13N5O4, MW 255.23 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Acyclovir EP Impurity Q (C9H13N5O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 255.23 g/mol, it falls into the medium-molecular-weight range. 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), Acyclovir EP Impurity Q 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.
