Chemical Structure

Phoxim-d5 (phenyl-d5) (mixture of isomers) CAS CATO-CCPD103123 chemical structure

Description

The occurrence of Phoxim-d5 (phenyl-d5) (mixture of isomers) is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Phoxim-d5 (phenyl-d5) (mixture of isomers) (CAS CATO-CCPD103123), molecular formula C12H10D5N2O3PS and molecular weight 303.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphonate group, a hydroxyl group, an ether linkage, Phoxim-d5 (phenyl-d5) (mixture of isomers) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
