Fluorescein-6-carbonyl-Tyr-Val-Ala-DL-Asp(OMe)-fluoromethylketone CAS 1926163-69-0

Description

The occurrence of Fluorescein-6-carbonyl-Tyr-Val-Ala-DL-Asp(OMe)-fluoromethylketone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Fluorescein-6-carbonyl-Tyr-Val-Ala-DL-Asp(OMe)-fluoromethylketone (CAS 1926163-69-0), a certified reference material (molecular formula C44H43FN4O13, MW 854.84 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Fluorescein-6-carbonyl-Tyr-Val-Ala-DL-Asp(OMe)-fluoromethylketone is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 854.84 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.

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.
