25518-49-4 Isobutyryl-1-carnitine Ammonium, (3-carboxy-2-hydroxypropyl)trimethyl-, hydroxide, inner salt, isobutyrate, L- (S)-3-Carboxy-N,N,N-trimethyl-2-(2-methyl-1-oxopropoxy)-1-propanaminium, hydroxide, inner salt 1-Propanaminium, 3-carboxy-N,N,N-trimethyl-2-(2-methyl-1-oxopropoxy)-, inner salt, (R)- (9CI) BRN 4138517 Iso-butyryl-L(-)-carnitin [German] Isobutyryl-carnitine Isobutyryl-L-carnitine Iso-butyryl-L(-)-carnitin (CAS 25518-49-4), molecular formula C11H21NO4 and molecular weight 231.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H21NO4, 25518-49-4 Isobutyryl-1-carnitine Ammonium, (3-carboxy-2-hydroxypropyl)trimethyl-, hydroxide, inner salt, isobutyrate, L- (S)-3-Carboxy-N,N,N-trimethyl-2-(2-methyl-1-oxopropoxy)-1-propanaminium, hydroxide, inner salt 1-Propanaminium, 3-carboxy-N,N,N-trimethyl-2-(2-methyl-1-oxopropoxy)-, inner salt, (R)- (9CI) BRN 4138517 Iso-butyryl-L(-)-carnitin [German] Isobutyryl-carnitine Isobutyryl-L-carnitine Iso-butyryl-L(-)-carnitin contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 231.29 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.
