How Do You Spell O PHTHALDIALDEHYDE?

Pronunciation: [ˈə͡ʊ fθˌaldɪˈaldɪhˌa͡ɪd] (IPA)

The correct spelling of the word "o Phthaldialdehyde" may seem difficult due to its complex pronunciation. Using the IPA phonetic transcription, we can break it down into distinct sounds: /oʊ/ for the first syllable, which is often written as "oh"; /fθ/ for the "phth" sound, which is a combination of "f" and "th"; /æl/ for the next syllable; and /daɪˈæl.dəˌhaɪd/ for the final portion, which includes the compound word "aldehyde". Despite the complexity, proper spelling is important for clear communication in scientific settings.

O PHTHALDIALDEHYDE Meaning and Definition

1. o-Phthaldialdehyde (OPA) is an organic compound that belongs to the family of dialdehydes. It is a colorless crystalline solid with a characteristic aromatic odor. OPA is primarily used as a highly selective and sensitive reagent in various analytical techniques, especially for the determination of primary amines.

   In analytical chemistry, o-phthaldialdehyde is widely employed in a method called the OPA derivatization reaction. This reaction involves the reaction of o-phthaldialdehyde with primary amines, resulting in the formation of fluorescent derivatives. The produced derivatives are highly stable and exhibit intense fluorescence, making them suitable for quantification using fluorescence detection methods. This derivatization technique is commonly used for the analysis of amino acids, peptides, proteins, and other compounds containing primary amines.

   o-Phthaldialdehyde is preferred over other derivatizing agents due to its high sensitivity and specificity. It is highly selective towards primary amines as it forms stable derivatives only with compounds containing a free amino group. Additionally, o-phthaldialdehyde reacts rapidly, allowing for quick analysis.

   In summary, o-phthaldialdehyde, abbreviated as OPA, is a versatile compound used in analytical chemistry for its ability to selectively and sensitively detect primary amines. Its use in the OPA derivatization reaction has made it a crucial reagent in various analytical techniques, aiding in quantification and identification of amino acids, peptides, and proteins.

Etymology of O PHTHALDIALDEHYDE

The word "o Phthaldialdehyde" is a chemical compound name consisting of two parts: "o" and "Phthaldialdehyde".

The "o" in this context refers to the ortho- prefix, which is derived from the Greek word "orthos" meaning "straight" or "correct". It is commonly used in organic chemistry to indicate the positions of two substituents on a benzene ring, with ortho- representing a 1,2-disubstitution pattern.

"Phthaldialdehyde" is a compound made up of two components: "phthal" and "dialdehyde".

"Phthal" is derived from the word "phthalic", which originates from the molecule it is based on called phthalic acid. The phthalic acid is obtained by the oxidation of naphthalene, a hydrocarbon-based compound found in coal tar.
