INTRODUCTION
Sodium monochloroacetate (SMCA), or sodium chloroacetate, is the sodium salt of monochloroacetic acid. It is derived from the chlorination of acetic acid, followed by neutralization with sodium hydroxide. It is hygroscopic in nature and highly soluble in water.
It is valued for its reactive chloro group, making it a versatile chemical in organic synthesis. SMCA is toxic and corrosive, requiring proper safety precautions during handling.

Ginkgo Biloba 24% extract is a standardized herbal formulation derived from the leaves of the Ginkgo biloba tree, one of the oldest living tree species. The “24%” typically refers to the content of flavone glycosides, while the product may also contain 6% terpene lactones. These active constituents are responsible for its medicinal properties.
1,3-Dibromopropane is an organobromine compound. A bifunctional alkyl halide, it has two bromine leaving groups that can participate in substitution or elimination reactions. It is widely used as a an intermediate in production of wide range of products including pharmaceuticals, insecticides, quaternary Ammonium compounds, flavouring agents ,fragrances and in polymer chemistry.
Tributyltin Hydride (TBT-H) stabilized with BHT (butylated hydroxytoluene) is a tin-based organometallic compound commonly used in organic synthesis, especially in radical reactions. It is air-sensitive and decomposes to tributyltin oxide in presence of oxygen and light. It works by donating a hydrogen radical (H·) to a carbon radical intermediate.
2,4,6-Trimethylpyridine (also known as collidine) is a derivative of pyridine, featuring three methyl groups at the 2nd, 4th, and 6th positions. This compound is a colorless to yellow liquid with a strong, pungent odor. Due to its basicity and steric hindrance, it is widely used as a catalyst, solvent, and chemical intermediate in various industrial and pharmaceutical applications.
L-Phenylalanine (L-Phe) is an essential and proteinogenic amino acid that helps build proteins and produces brain chemicals like dopamine and norepinephrine. L-Phenylalanine is one of the 20 standard amino acids that form long chains called polypeptides (proteins).The body cannot produce it, so it must be obtained through diet or supplements.
L-carnitine Hydrochloride is a water soluble, stable salt form of L- Carnitine. It is a naturally occurring amino acid derivative. It is often used as a dietary supplement due to its role in energy production and fat metabolism.
Dimenhydrinate is an antihistamine drug commonly used to prevent and treat motion sickness, nausea, and vertigo. It is a combination of diphenhydramine and 8-chlorotheophylline, where the latter reduces the sedative effects of diphenhydramine. It is available in tablet, liquid, and injectable forms under various brand names.
o-Nitrophenyl Disulfide is a chemical compound used in organic chemistry and biochemistry. It is a disulfide derivative where two o-nitrophenyl groups are connected by a disulfide bond (-S-S-) It is used in various organic synthesis reactions, as a reagent in the preparation of thiol-reactive compounds, in pharmaceutical research and laboratory applications.
Tetrasodium pyrophosphate (TSPP) anhydrous is a white, crystalline or granular inorganic compound, soluble in water but insoluble in alcohol. TSPP is widely used in food, industrial, and cleaning applications due to its sequestrant, dispersing, buffering, and emulsifying properties.
