Voriconazole EP Impurity E (1R)-Isomer CAS 35963-20-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Voriconazole EP Impurity E (1R)-Isomer.

CATO supplies Voriconazole EP Impurity E (1R)-Isomer (CAS 35963-20-3), a pharmacopoeial impurity reference standard (molecular formula C10H16O4S, MW 232.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Voriconazole EP Impurity E (1R)-Isomer (C10H16O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 232.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Voriconazole EP Impurity E (1R)-Isomer 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.
