Chemical Structure

Boc-Pro-Leu-Val-OMe (A-2260.0250) CAS 13650-75-4 chemical structure

Description

The occurrence of Boc-Pro-Leu-Val-OMe (A-2260.0250) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Boc-Pro-Leu-Val-OMe (A-2260.0250) (CAS 13650-75-4), a certified reference material (molecular formula C22H39N3O6, MW 441.56 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Boc-Pro-Leu-Val-OMe (A-2260.0250) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 441.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
