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.
CATO supplies 4-Methylumbelliferyl 4-Guanidinobenzoate Hydrochloride (CAS 34197-46-1), a certified reference material (molecular formula C18H15N3O4HCl, MW 373.79 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methylumbelliferyl 4-Guanidinobenzoate Hydrochloride (C18H15N3O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-Methylumbelliferyl 4-Guanidinobenzoate Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
