Description

(3-nitrobenzoyl)alanine, also known as **N-(3-nitrobenzoyl)alanine**, is an **amino acid derivative** created by attaching a 3-nitrobenzoyl group to the amino group of alanine.

**Structure and Properties:**

* **Structure:** It is a white to off-white solid with a molecular formula of C10H10N2O5.
* **Properties:** Its exact properties depend on the specific application and the synthetic method used. It is likely to be a stable compound, but detailed information about its melting point, solubility, and other properties is not readily available in public databases.

**Importance in Research:**

While (3-nitrobenzoyl)alanine itself might not be a widely studied compound, it is **important in research for several reasons:**

* **Synthetic precursor:** It could be a useful starting material in the synthesis of other complex organic molecules, particularly those containing the 3-nitrobenzoyl moiety.
* **Analytical reagent:** It might be used as a reagent for detecting or quantifying certain biomolecules, potentially through its ability to react with specific functional groups.
* **Pharmaceutical research:** Derivatives of (3-nitrobenzoyl)alanine could potentially exhibit biological activity relevant to pharmaceutical research, such as antibacterial, antiviral, or anticancer properties. This is due to the 3-nitrobenzoyl group which is often found in pharmacologically active compounds.

**Lack of Extensive Research:**

It's worth noting that there is limited information available about (3-nitrobenzoyl)alanine's specific applications and research history. This suggests it might be a less widely explored compound or a recently synthesized derivative.

Huntington Disease
A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset.
