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 Falecalcitriol impurity 5.
Falecalcitriol impurity 5 (CAS CATO-C4X-31415) is a certified pharmaceutical impurity reference standard with the molecular formula C18H26F6O and a molecular weight of 372.39 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, Falecalcitriol impurity 5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Falecalcitriol impurity 5 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.
