Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(1,2-Dithiolan-3-yl)pentanoyl-hydrazide (CAS 145459-24-1), molecular formula C8H16N2OS2 and molecular weight 220.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H16N2OS2, (1,2-Dithiolan-3-yl)pentanoyl-hydrazide contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 220.36 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.
