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.
Terbuthylazine D5 (ethyl D5) (CAS 222986-60-9), molecular formula C9H11D5ClN5 and molecular weight 234.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Terbuthylazine D5 (ethyl D5) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Terbuthylazine D5 (ethyl D5) 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.
