Description

1-Imidazolidinecarbonyl Chloride, 3-Acetyl-2,5-Dioxo- (9Ci) is a specialized heterocyclic building block characterized by its reactive carbonyl chloride and acetyl-dioxoimidazolidine functional groups. This compound matters as a versatile intermediate for synthesizing complex molecules, enabling the introduction of the imidazolidinecarbonyl moiety into target structures. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Key intermediate in the synthesis of pharmaceutical candidates, particularly those targeting enzyme inhibition.
• Building block for advanced agrochemicals, such as herbicides and fungicides with novel modes of action.
• Precursor for functionalized polymers and materials science applications requiring specific heterocyclic motifs.
• Research chemical for developing new synthetic methodologies and exploring structure-activity relationships (SAR).
• Starting material for the preparation of specialized dyes and photoactive compounds.
• Reagent in peptide mimetic and bio-conjugation chemistry due to its reactive acid chloride group.

Quality Control

Our 1-Imidazolidinecarbonyl Chloride, 3-Acetyl-2,5-Dioxo- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
