5-(Benzyl(tert-butoxycarbonyl)amino)-4,4-difluoro-2-methylpentanoic acid CAS 2101206-20-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(Benzyl(tert-butoxycarbonyl)amino)-4,4-difluoro-2-methylpentanoic acid.

CATO supplies 5-(Benzyl(tert-butoxycarbonyl)amino)-4,4-difluoro-2-methylpentanoic acid (CAS 2101206-20-4), a certified reference material (molecular formula C18H25F2NO4, MW 357.39 g/mol) for analytical method development and quality control.

The molecular framework of 5-(Benzyl(tert-butoxycarbonyl)amino)-4,4-difluoro-2-methylpentanoic acid (C18H25F2NO4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.

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 5-(Benzyl(tert-butoxycarbonyl)amino)-4,4-difluoro-2-methylpentanoic acid 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.
