Chemical Structure

N,N'-Bis(3-methylbutyl)propanediamide CAS 126947-45-3 chemical structure

Description

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

N,N'-Bis(3-methylbutyl)propanediamide (CAS 126947-45-3), molecular formula C13H26N2O2 and molecular weight 242.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H26N2O2, N,N'-Bis(3-methylbutyl)propanediamide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 242.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
