Benzaldehydes

Benzaldehyde (C6H5CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful.

4-Anisaldehyde, or '''p-Anisaldehyde', is an organic compound with the formula CH3OC6H4CHO. The molecule consists of a benzene ring with a formyl and a methoxy group. It is a colorless liquid with a strong aroma. It provides sweet, floral and strong aniseed odor. Two isomers of 4-anisaldehyde are known, ortho-anisaldehyde and meta''-anisaldehyde. They are less commonly encountered.

Piperonal, also known as heliotropin, is an organic compound which is commonly found in fragrances and flavors. The molecule is structurally related to other aromatic aldehydes such as benzaldehyde and vanillin. The methylenedioxyphenyl group is found in other fragrances.

Cuminaldehyde (4-isopropylbenzaldehyde) is a natural organic compound with the molecular formula C10H12O. It is a benzaldehyde with an isopropyl group substituted in the 4-position.

4-Nitrobenzaldehyde is an organic compound with the formula . It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde.

Veratraldehyde (3,4-dimethoxybenzaldehyde) is an organic compound with the formula . Several isomers are known. The compound is widely used as a flavorant and odorant. The compound is structurally related to benzaldehyde, with two methoxy groups.

3-Nitrobenzaldehyde is an organic compound with the formula . It is one of three isomers of nitrobenzaldehyde. It contains a nitro group meta-substituted to the aldehyde.

2,5-Dimethoxybenzaldehyde is an organic compound and a benzaldehyde derivative. One of its uses is the production of 2,5-dimethoxyphenethylamine, also known as 2C-H. 2C-H is used to produce many other substituted phenethylamines such as 2C-B, 2C-I and 2C-C.

Nitrobenzaldehyde may refer to any of the three isomeric chemical compounds :

2-Nitrobenzaldehyde is an organic compound with the formula . It is one of three isomers of nitrobenzaldehyde. It contains a nitro group adjacent to the formyl group.

4-Methylbenzaldehyde is the aromatic aldehyde with the formula CH3C6H4CHO. It is a colorless liquid. Commercially available, it may be prepared from the Friedel-Crafts formylation of toluene with carbon monoxide and hydrogen chloride under Gattermann-Koch conditions. 4-Methylbenzaldehyde has a cherry-like scent similar to benzaldehyde, and finds some use in the fragrance industry.

'''para-Dimethylaminobenzaldehyde''' is an organic compound containing amine and aldehyde moieties which is used in Ehrlich's reagent and Kovac's reagent to test for indoles. The carbonyl group typically reacts with the electron rich 2-position of the indole but may also react at the C-3 or N-1 positions. It may also be used for determination of hydrazine.

Phthalaldehyde (sometimes also '''o-phthalaldehyde or ortho-phthalaldehyde, OPA''') is the chemical compound with the formula C6H4(CHO)2. It is one of three isomers of benzene dicarbaldehyde, related to phthalic acid. This pale yellow solid is a building block in the synthesis of heterocyclic compounds and a reagent in the analysis of amino acids. OPA dissolves in water solution at pH < 11.5. Its solutions degrade upon UV illumination and exposure to air.

3-Acetyl-6-methoxybenzaldehyde is a chemical compound found in the leaves of Encelia farinosa.

4-Ethylbenzaldehye is a derivative of benzaldehyde.

2-Chlorobenzaldehyde ('''o-chlorobenzaldehyde''') is an organic compound with the formula . It is one of three isomeric monochlorinated benzaldehyde. 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers. Whereas benzaldehyde is prone to autoxidation, the 2-chloro derivatives are more air-stable.

2-Diphenylphosphinobenzaldehyde is a phosphine ligand with the formula (C6H5)2PC6H4CHO. It is a yellow solid that dissolves in common organic solvents.

3-Bromobenzaldehyde is an isomer of bromobenzaldehyde. It is a colorless viscous liquid.

Fluorobenzaldehyde is a group of three constitutional isomers of fluorinated benzaldehyde.

4-Chlorobenzaldehyde ('''p-Chlorobenzaldehyde''') is an organic compound with the formula . It is one of three isomeric monochlorinated benzaldehydes.

Chlorobenzaldehyde may refer to:

4-Carboxybenzaldehyde (CBA) is an organic compound with the formula OCHC6H4CO2H. It consists of a benzene ring substituted with both an aldehyde and a carboxylic acid, with these functional groups on opposite corners of the ring. This compound is formed in 0.5% yield as a byproduct in the production terephthalic acid from p-xylene. Since approximately 40,000,000 tons of terephthalic acid are produced per year, CBA is a relatively large scale industrial chemical.

Bromobenzaldehydes are any of three organic compounds with the formula BrC6H4COH, consisting of a formyl group and a bromine atom attached to a central benzene ring. They can be considered as brominated derivatives of benzaldehyde, or as formylated derivatives of bromobenzene.

2-Aminobenzaldehyde is an organic compound with the formula C6H4(NH2)CHO. It is one of three isomers of aminobenzaldehyde. It is a low-melting yellow solid that is soluble in water.

Hernandaline is one of a class of quinoline alkaloids with chemical formula C29H31NO7 C29H31NO7 . This compound has been isolated from the stem bark of Hernandia ovigera (Hernandiaceae). Studies have established than hernandaline has hypotensive activity. Its optical rotation is [\alpha]_D^{20} = +36.5°.
