Chemical Structure

3-tert-Butyl-5-isothiocyanato-1-methyl-1H-pyrazole CAS 1349718-07-5 chemical structure

Description

3-tert-Butyl-5-isothiocyanato-1-methyl-1H-pyrazole (CAS 1349718-07-5), molecular formula C9H13N3S and molecular weight 195.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H13N3S, 3-tert-Butyl-5-isothiocyanato-1-methyl-1H-pyrazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
