Fmoc-Phe(4-Cl)-OH CAS 175453-08-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-Phe(4-Cl)-OH.

Fmoc-Phe(4-Cl)-OH (CAS 175453-08-4) is a high-purity analytical reference standard with the molecular formula C24H20ClNO4 and a molecular weight of 421.87 g/mol.

Based on its molecular formula C24H20ClNO4, Fmoc-Phe(4-Cl)-OH contains a flavonoid 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 421.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures Fmoc-Phe(4-Cl)-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.
