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 (R)-2-Amino-3,3-difluoro-4-methylpentanoic acid.
(R)-2-Amino-3,3-difluoro-4-methylpentanoic acid (CAS 2095886-36-3) is a high-purity analytical reference standard with the molecular formula C6H11F2NO2 and a molecular weight of 167.15 g/mol.
The molecular framework of (R)-2-Amino-3,3-difluoro-4-methylpentanoic acid (C6H11F2NO2) is characterized by an amide group, a carboxylic acid 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.
As a certified reference material (CRM), (R)-2-Amino-3,3-difluoro-4-methylpentanoic acid 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.
