Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1209.40 g/mol gives Leuprorelin EP Impurity H distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Leuprorelin EP Impurity H (CAS 112710-58-4) is a certified pharmaceutical impurity reference standard with the molecular formula C59H84N16O12 and a molecular weight of 1209.40 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Leuprorelin EP Impurity H is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1209.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Leuprorelin EP Impurity H 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.
