3-(1-Methyl-1h-pyrazole-5-amido)benzoic acid CAS 1002032-75-8

Description

Compared with other compounds in its class, the molecular weight of 245.23 g/mol gives 3-(1-Methyl-1h-pyrazole-5-amido)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(1-Methyl-1h-pyrazole-5-amido)benzoic acid (CAS 1002032-75-8), molecular formula C12H11N3O3 and molecular weight 245.23 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, 3-(1-Methyl-1h-pyrazole-5-amido)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
