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 (2R,3S)-Methyl 2-amino-3-hydroxy-4-methylpentanoate.
(2R,3S)-Methyl 2-amino-3-hydroxy-4-methylpentanoate (CAS 761344-55-2), molecular formula C7H15NO3 and molecular weight 161.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2R,3S)-Methyl 2-amino-3-hydroxy-4-methylpentanoate (C7H15NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
