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 H-D-Thr-OBzl · oxalate (1:1).
H-D-Thr-OBzl · oxalate (1:1) (CAS 201274-09-1), molecular formula C11H15NO3C2H2O4 and molecular weight 299.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of H-D-Thr-OBzl · oxalate (1:1) (C11H15NO3C2H2O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-D-Thr-OBzl · oxalate (1:1) 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.
