Chemical Structure

H-Leu-Leu-Leu-NH? CAS 73237-77-1 chemical structure

Description

The occurrence of H-Leu-Leu-Leu-NH? is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

H-Leu-Leu-Leu-NH? (CAS 73237-77-1) is a high-purity analytical reference standard with the molecular formula C18H36N4O3 and a molecular weight of 356.50 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, H-Leu-Leu-Leu-NH? is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.50 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.

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.

As a certified reference material (CRM), H-Leu-Leu-Leu-NH? meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
