Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
H-Thr-Phe-OH TFA (CAS 16875-27-7(free base)) is a high-purity analytical reference standard with the molecular formula C13H18N2O4C2HF3O2 and a molecular weight of 380.32 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, H-Thr-Phe-OH TFA is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.32 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).
CATO manufactures H-Thr-Phe-OH TFA 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.
