1-Methyl-2-naphthalenecarboxaldehyde

Description:

1-Methyl-2-naphthalenecarboxaldehyde, with the CAS number 35699-45-7, is an organic compound characterized by its naphthalene structure, which consists of two fused aromatic rings. This compound features a methyl group and a formyl group (aldehyde) attached to the naphthalene framework, specifically at the 1 and 2 positions, respectively. It is a colorless to pale yellow liquid with a distinct aromatic odor, typical of naphthalene derivatives. The compound is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic nature. 1-Methyl-2-naphthalenecarboxaldehyde is primarily used in the synthesis of various organic compounds and as a fragrance ingredient in perfumery. It may also serve as an intermediate in the production of pharmaceuticals and agrochemicals. As with many aldehydes, it can undergo reactions typical of this functional group, including oxidation and condensation reactions, making it a versatile building block in organic synthesis. Safety precautions should be observed when handling this compound, as it may pose health risks if inhaled or ingested.

1-Methylnaphthalene-2-carbaldehyde is a compound that can be found in acetonitrile. The molecule has two isomers, which are distinguished by the position of the methyl group on the ring. The 1-methylnaphthalene-2-carbaldehyde molecule is an organic compound with a molecular weight of 136.19 g/mol and a boiling point of 141°C at 0.1 mmHg. It has a photoisomerization quantum yield of 0.05 and fluorescence lifetimes of 4 to 5 nanoseconds, which are both relatively low. The molecule's singlet state lifetime is about half that of its triplet state lifetime, although it has been shown to have a higher quantum yield for this state than for its ground state. This means that the singlet state is more stable than the ground state, so it will remain in this state longer before emitting light or changing back to its ground state. This property makes
