Compound 4-tert-Butylcalix[4]arene C44H56O4 CAS 60705-62-6

Products Description

What is Compound 4-tert-Butylcalix[4]arene C44H56O4 CAS 60705-62-6?

4-tert-Butylcalix[4]arene (CAS No.: 60705-62-6) is a supramolecular compound with a unique cup-shaped structure. Its chemical name is 4-tert-butylcalix[4]arene, with a molecular formula of C₄₄H₅₆O₄ and a molecular weight of 648.91 g/mol. The molecule consists of four p-tert-butylphenol units linked via methylene bridges, forming a cyclic structure with a highly symmetrical cup-shaped conformation.

This compound appears as a white to off-white crystalline powder that remains stable in air and does not deliquesce easily. It has a melting point of approximately 280–285°C and maintains stability under normal temperature and pressure conditions. However, it should be kept away from strong oxidizing agents to prevent potential reactions.

Uses

Supramolecular chemistry:
Molecular recognition: 4-tert-Butylcalix[4]arene uses the cup-shaped cavity to form a host-guest inclusion complex with metal ions and organic molecules for separation, catalysis or sensing. For example, its derivatives can selectively recognize potassium ions or aromatic compounds.
Catalytic carrier: As a catalyst carrier, it improves the reaction selectivity through the cavity confinement effect, such as enhancing the acid catalytic activity in the esterification reaction.
Material science:
Adsorption material: used to prepare high-efficiency adsorbents to remove heavy metal ions or organic pollutants from wastewater.
Liquid crystal material: By introducing flexible chain segments, its liquid crystal phase behavior can be regulated for display technology or information storage.

Safety Information

Toxicity and Hazards:
Acute toxicity: Rat oral LD₅₀ > 2000 mg/kg, low toxicity.
Health Hazards: Dust may irritate the respiratory tract, and skin contact may cause mild allergic reactions.
Environmental Risks: Low toxicity to aquatic organisms, but direct discharge into water bodies should be avoided.
Protective Measures:
Wear dust masks, protective gloves and goggles during operation to avoid inhalation of dust or skin contact.
Store in a cool, dry place, away from fire and oxidants, and store separately from acids and alkalis.
Emergency Treatment:
Use sand or activated carbon to absorb in case of leakage to avoid entering the sewer.
Dry powder, carbon dioxide or foam fire extinguishers can be used for fire extinguishing.
