Chemical Structure

D CAS 139657-63-9 chemical structure

Description

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.

D (CAS 139657-63-9) is a high-purity analytical reference standard with the molecular formula C4[13C]H10O5 and a molecular weight of 151.12 g/mol.

The molecular framework of D (C4[13C]H10O5) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a certified reference material (CRM), D 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.
