Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
3-Amino-5-methyl-hexanoic acid 3-amino-5-methylhexanoic acid 3653-34-7 d,l-beta-homoleucine dl-beta-homoleucine (CAS 3653-34-7), molecular formula C7H15NO2 and molecular weight 145.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Amino-5-methyl-hexanoic acid 3-amino-5-methylhexanoic acid 3653-34-7 d,l-beta-homoleucine dl-beta-homoleucine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.20 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.
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.
