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)-3-phenyl-isoserine methyl ester (2r,3s)-3-phenylisoserine methyl ester (2r,3s)-methyl 3-amino-2-hydroxy-3-phenylpropanoate (alphar,betas)-rel-beta-amino-alpha-hydroxybenzenepropanoic acid methyl ester 131968-74-6 2r,3s pound(c)-phenylisoserine methylester.

(2R,3S)-3-phenyl-isoserine methyl ester (2r,3s)-3-phenylisoserine methyl ester (2r,3s)-methyl 3-amino-2-hydroxy-3-phenylpropanoate (alphar,betas)-rel-beta-amino-alpha-hydroxybenzenepropanoic acid methyl ester 131968-74-6 2r,3s pound(c)-phenylisoserine methylester (CAS 131968-74-6) is a high-purity analytical reference standard with the molecular formula C10H13NO3 and a molecular weight of 195.22 g/mol.

The molecular framework of (2R,3S)-3-phenyl-isoserine methyl ester (2r,3s)-3-phenylisoserine methyl ester (2r,3s)-methyl 3-amino-2-hydroxy-3-phenylpropanoate (alphar,betas)-rel-beta-amino-alpha-hydroxybenzenepropanoic acid methyl ester 131968-74-6 2r,3s pound(c)-phenylisoserine methylester (C10H13NO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (2R,3S)-3-phenyl-isoserine methyl ester (2r,3s)-3-phenylisoserine methyl ester (2r,3s)-methyl 3-amino-2-hydroxy-3-phenylpropanoate (alphar,betas)-rel-beta-amino-alpha-hydroxybenzenepropanoic acid methyl ester 131968-74-6 2r,3s pound(c)-phenylisoserine methylester 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.
