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.

1,3-Dihydro-1,3-dioxoisoindole-15N 53510-88-6 Phthalimide-15N potassium salt Potassium phthalimide-15N (CAS 53510-88-6), molecular formula C8H10K[15N]O2 and molecular weight 192.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,3-Dihydro-1,3-dioxoisoindole-15N 53510-88-6 Phthalimide-15N potassium salt Potassium phthalimide-15N (C8H10K[15N]O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 192.26 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.

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.
