Chemical Structure
Description
(±)-1-Phenylethan-1,2,2,2-d4-ol (CAS 90162-44-0), molecular formula C8H6D4O and molecular weight 126.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (±)-1-Phenylethan-1,2,2,2-d4-ol (C8H6D4O) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 126.19 g/mol, it falls into the low-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
