Chemical Structure
Description
3,5-Dichlorobiphenyl-2',3',4',5',6'-d5 (CAS 1276197-28-4), molecular formula C5H6D3NO4 and molecular weight 150.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3,5-Dichlorobiphenyl-2',3',4',5',6'-d5 (C5H6D3NO4) contains deuterium isotope labeling, a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 150.15 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
