Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 344.45 g/mol gives Boc-Ile-Ile-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Boc-Ile-Ile-OH (CAS 69541-98-6), a certified reference material (molecular formula C17H32N2O5, MW 344.45 g/mol) for analytical method development and quality control.
Structurally, Boc-Ile-Ile-OH (C17H32N2O5) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 344.45 g/mol, it falls into the moderately-high-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.
