Chemical Structure
Description
The occurrence of Fmoc-6-chloro-D-tryptophan is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fmoc-6-chloro-D-tryptophan (CAS 925916-73-0), a certified reference material (molecular formula C26H21ClN2O4, MW 460.91 g/mol) for analytical method development and quality control.
Based on its molecular formula C26H21ClN2O4, Fmoc-6-chloro-D-tryptophan contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 460.91 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-6-chloro-D-tryptophan 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.
