2-(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)-2-methyl-N-(p-tolyl)hydrazine-1-carboxamide CAS 318284-29-6

Description

Compared with other compounds in its class, the molecular weight of 328.20 g/mol gives 2-(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)-2-methyl-N-(p-tolyl)hydrazine-1-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)-2-methyl-N-(p-tolyl)hydrazine-1-carboxamide (CAS 318284-29-6), molecular formula C13H15Cl2N5O and molecular weight 328.20 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3,4-Dichloro-1-methyl-1H-pyrazol-5-yl)-2-methyl-N-(p-tolyl)hydrazine-1-carboxamide (C13H15Cl2N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
