Chemical Structure

Urea-13C,15N2 CAS 78405-35-3 chemical structure

Description

CATO supplies Urea-13C,15N2 (CAS 78405-35-3), a certified reference material (molecular formula [13C]H4[15N]2O, MW 63.03 g/mol) for analytical method development and quality control.

Urea-13C,15N2 ([13C]H4[15N]2O) contains a hydroxyl group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
