Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 131.18 g/mol gives 3-Amino-1-(2-methylpropyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Amino-1-(2-methylpropyl)urea (CAS 79353-74-5) is a high-purity analytical reference standard with the molecular formula C5H13N3O and a molecular weight of 131.18 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, 3-Amino-1-(2-methylpropyl)urea is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 131.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
