Chemical Structure

1-Methyluric Acid-[13C4,15N3] CAS 1173022-91-7 chemical structure

Description

CATO supplies 1-Methyluric Acid-[13C4,15N3] (CAS 1173022-91-7), a certified reference material (molecular formula C2[13C]4H6N[15N]3O3, MW 189.09 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Methyluric Acid-[13C4,15N3] is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 189.09 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
