Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including m-Xylene-d4 (ring-d4).
m-Xylene-d4 (ring-d4) (CAS 425420-97-9) is a high-purity analytical reference standard with the molecular formula C8H6D4 and a molecular weight of 110.19 g/mol.
Owing to deuterium isotope labeling, an aromatic ring system, m-Xylene-d4 (ring-d4) is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures m-Xylene-d4 (ring-d4) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
