4-(Methyl((1-methyl-1H-pyrazol-5-yl)methyl)amino)-4-oxobut-2-enoic acid CAS 1006334-17-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Methyl((1-methyl-1H-pyrazol-5-yl)methyl)amino)-4-oxobut-2-enoic acid.

4-(Methyl((1-methyl-1H-pyrazol-5-yl)methyl)amino)-4-oxobut-2-enoic acid (CAS 1006334-17-3), molecular formula C10H13N3O3 and molecular weight 223.23 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, 4-(Methyl((1-methyl-1H-pyrazol-5-yl)methyl)amino)-4-oxobut-2-enoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 223.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
