Description
CATO supplies 1,2-Propanediol, polymer with N1-(2-aminoethyl)-1,2-ethanediamine (CAS 68492-63-7), a certified reference material (molecular formula C4H13N3C3H8O2, MW 179.26 g/mol) for analytical method development and quality control.
Structurally, 1,2-Propanediol, polymer with N1-(2-aminoethyl)-1,2-ethanediamine (C4H13N3C3H8O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 179.26 g/mol, it falls into the medium-molecular-weight range. 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.
