Chemical Structure

H-Leu-OtBu · HCl CAS 2748-02-9 chemical structure

Description

CATO supplies H-Leu-OtBu · HCl (CAS 2748-02-9), a certified reference material (molecular formula C10H21NO2HCl, MW 223.74 g/mol) for analytical method development and quality control.

The molecular framework of H-Leu-OtBu · HCl (C10H21NO2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

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.

As a certified reference material (CRM), H-Leu-OtBu · HCl 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.
