6-hydroxy-2-methoxypyrimidine-4-carboxylic acid CAS 1123546-30-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-hydroxy-2-methoxypyrimidine-4-carboxylic acid.

6-hydroxy-2-methoxypyrimidine-4-carboxylic acid (CAS 1123546-30-4), molecular formula C6H6N2O4 and molecular weight 170.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 6-hydroxy-2-methoxypyrimidine-4-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.12 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.
