2-(2-Isopropylpyrazol-3-yl)pyridine-3-carboxylic acid CAS 1437795-13-5

Description

Compared with other compounds in its class, the molecular weight of 231.25 g/mol gives 2-(2-Isopropylpyrazol-3-yl)pyridine-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Isopropylpyrazol-3-yl)pyridine-3-carboxylic acid (CAS 1437795-13-5) is a high-purity analytical reference standard with the molecular formula C12H13N3O2 and a molecular weight of 231.25 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(2-Isopropylpyrazol-3-yl)pyridine-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.25 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.
