Chemical Structure

Valaciclovir EP Impurity H(hydrochloride) CAS 84499-63-8 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 Valaciclovir EP Impurity H(hydrochloride).

Valaciclovir EP Impurity H(hydrochloride) (CAS 84499-63-8) is a certified pharmaceutical impurity reference standard with the molecular formula C11H16N6O4HCl and a molecular weight of 332.75 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Valaciclovir EP Impurity H(hydrochloride) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.75 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.

CATO manufactures Valaciclovir EP Impurity H(hydrochloride) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
