CAS 643-79-8

Phthalaldehyde

Description:

Phthalaldehyde, also known as 1,2-benzenedicarboxaldehyde, is an organic compound with the chemical formula C8H6O2 and the CAS number 643-79-8. It is characterized by the presence of two aldehyde functional groups attached to a benzene ring, which contributes to its reactivity and utility in various chemical applications. Phthalaldehyde is typically a colorless to pale yellow liquid with a strong, pungent odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water. This compound is primarily used as a precursor in the synthesis of various chemicals, including pharmaceuticals and dyes, and as a cross-linking agent in polymer chemistry. Additionally, phthalaldehyde exhibits properties that make it useful in the field of fluorescence, as it can form fluorescent derivatives. However, it is important to handle this substance with care, as it may pose health risks upon exposure, including irritation to the skin, eyes, and respiratory system.

Phthalaldehyde

CAS: 643-79-8

Phthalaldehyde is a disinfectant that is used for the prevention of microbial contamination in the manufacturing process of pharmaceuticals, cosmetics, and many other products. It has been shown to inhibit the growth of bacteria by inhibiting protein synthesis. The mechanism of action is thought to be due to its reaction with amino acids, which are important for protein synthesis. Phthalaldehyde also reacts with benzalkonium chloride to form a fluorescent derivative, which can be detected using fluorescence detectors or LC-MS/MS methods. The use of this compound as a fluorescence probe allows for the detection of probiotic bacteria in nutrient solutions without the need for expensive equipment or complicated analytical methods.
