Chemical Structure
Description
As a certified reference material (CRM), p-Xylene-d4 (ring-d4) 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.
p-Xylene-d4 (ring-d4) (CAS 16034-43-8), molecular formula C8H6D4 and molecular weight 110.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of p-Xylene-d4 (ring-d4) (C8H6D4) is characterized by deuterium isotope labeling, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, 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.
