1-Hydroxy-4-nitrobenzene-13C3 4-Hydroxy-1-nitrobenzene-13C3 4-Hydroxynitrobenzene-13C3 4-Nitrophenol-1,2,6-13C3 93628-02-5 NSC 1317-13C3 Niphen-13C3 p-Hydroxynitrobenzene-13C3 p-Nitrophenol-13C3 CAS 93628-02-5 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Hydroxy-4-nitrobenzene-13C3 4-Hydroxy-1-nitrobenzene-13C3 4-Hydroxynitrobenzene-13C3 4-Nitrophenol-1,2,6-13C3 93628-02-5 NSC 1317-13C3 Niphen-13C3 p-Hydroxynitrobenzene-13C3 p-Nitrophenol-13C3 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.11 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.

1-Hydroxy-4-nitrobenzene-13C3 4-Hydroxy-1-nitrobenzene-13C3 4-Hydroxynitrobenzene-13C3 4-Nitrophenol-1,2,6-13C3 93628-02-5 NSC 1317-13C3 Niphen-13C3 p-Hydroxynitrobenzene-13C3 p-Nitrophenol-13C3 (CAS 93628-02-5), molecular formula C3[13C]3H8NO3 and molecular weight 145.11 g/mol, is a CATO reference standard with documented purity and traceability.

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.
