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 Fmoc-His(Clt)-OH.
Fmoc-His(Clt)-OH (CAS 224032-19-3), molecular formula C40H32ClN3O4 and molecular weight 654.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Fmoc-His(Clt)-OH (C40H32ClN3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 26.0, corresponding to approximately 26 ring(s) or double-bond equivalent(s). With a molecular weight of 654.15 g/mol, it falls into the high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Fmoc-His(Clt)-OH 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.
