Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(Sec-butyl)-4-iodo-3,5-dimethyl-1h-pyrazole (CAS 1540375-17-4), molecular formula C9H15IN2 and molecular weight 278.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H15IN2, 1-(Sec-butyl)-4-iodo-3,5-dimethyl-1h-pyrazole contains a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
