Chemical Structure

Methyl 3-amino-1-isopropyl-1H-pyrazole-4-carboxylate hydrochloride CAS 1823441-75-3 chemical structure

Description

The occurrence of Methyl 3-amino-1-isopropyl-1H-pyrazole-4-carboxylate hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 3-amino-1-isopropyl-1H-pyrazole-4-carboxylate hydrochloride (CAS 1823441-75-3), molecular formula C8H13N3O2HCl and molecular weight 219.67 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 3-amino-1-isopropyl-1H-pyrazole-4-carboxylate hydrochloride (C8H13N3O2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 219.67 g/mol, it falls into the medium-molecular-weight range. 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.
