Buy factory price Glacial Acetic Acid CAS NO. 64-19-7 wholesale Purchase Glacial Acetic Acid | CAS No. 64-19-7 | Wholesale Prices Buy Glacial Acetic Acid at Factory Prices Buy factory price Glacial Acetic Acid CAS NO. 64-19-7 wholesale, systematically known as ethanoic acid, is a colorless, acidic liquid with the chemical formula CH?COOH (also written as CH?CO?H, C?H?O?, or HC?H?O?). This substance is highly concentrated and differs from vinegar, which contains at least 4% acetic acid by volume, making acetic acid the primary component of vinegar aside from water and trace elements. Characteristics and Uses Glacial acetic acid is the second simplest carboxylic acid, following formic acid, and features a methyl functional group. It plays a critical role as an industrial and chemical reagent. Its primary applications include:

• Cellulose Acetate Production: Used in the manufacture of photographic film.
• Polyvinyl Acetate Production: Essential for making wood glue and various synthetic fibers and fabrics.
• Household Use: Found in descaling agents.
• Food Industry: Regulated as a food additive (E260), it acts as an acidity regulator and condiment.
• Biochemistry: The acetyl group, derived from acetic acid, is vital for all forms of life, particularly in carbohydrate and fat metabolism when bound to coenzyme A.

Global Production and Supply The global demand for acetic acid is approximately 6.5 million metric tons annually, with around 1.5 million tons sourced from recycling. The remainder is produced from methanol. Vinegar, primarily composed of dilute acetic acid, is typically produced via fermentation and subsequent ethanol oxidation. Terminology and Properties

• Trivial Name: Acetic Acid
• Systematic Name: Ethanoic Acid
• Melting Point: 16-16.5°C
• Boiling Point: 117-118°C

Purchase Nitric Acid | CAS No. 7697-37-2 | Factory Prices Wholesale Buy Nitric Acid at Factory Prices Buy factory price Nitric acid / CAS NO. 7697-37-2 wholesale , with the chemical formula HNO?, is a highly corrosive mineral acid. It is typically colorless but can appear yellow over time due to decomposition into nitrogen oxides. Most commercially available nitric acid is a 68% solution in water. Solutions with more than 86% HNO? are classified as fuming nitric acid, which can be further categorized into red fuming nitric acid (concentrations above 86%) and white fuming nitric acid (concentrations above 95%). Uses and Applications Nitric acid is primarily used for nitration, the process of introducing a nitro group into an organic molecule. This process results in nitro compounds, some of which are sensitive explosives, while others are stable enough for use in munitions, demolition, and as pigments in inks and dyes. Nitric acid is also a potent oxidizing agent utilized in various industrial applications.Buy factory price Nitric acid / CAS NO. 7697-37-2 wholesale Product Specifications

Purchase Paraformaldehyde at Factory Prices | CAS No. 30525-89-4 | Wholesale Buy Paraformaldehyde (PFA) at Factory Prices Buy factory price Paraformaldehyde/ CAS NO. 30525-89-4 wholesale Paraformaldehyde is the smallest polyoxymethylene polymer, consisting of formaldehyde units typically ranging from 8 to 100. It is a white, powdery substance that often has a faint formaldehyde odor due to decomposition. As a polyacetal, paraformaldehyde is used in various industrial and scientific applications. Buy factory price Paraformaldehyde/ CAS NO. 30525-89-4 wholesale. Synthesis of Paraformaldehyde Paraformaldehyde is formed gradually in aqueous formaldehyde solutions, especially when stored in cold conditions. Formalin, a common solution containing formaldehyde, mostly contains short chains of polyformaldehyde rather than monomeric formaldehyde. To control polymerization, a small amount of methanol is typically added as a stabilizer. Buy factory price Paraformaldehyde/ CAS NO. 30525-89-4 wholesale. Reactions and Uses Paraformaldehyde can be depolymerized into formaldehyde gas through dry heating or into a formaldehyde solution using water in the presence of a base, acid, or heat. This high-purity formaldehyde is used in microscopy and histology as a fixative. The gas produced from dry heating paraformaldehyde is flammable.

• Fumigant, Disinfectant, and Fungicide: The formaldehyde obtained from paraformaldehyde is used for these purposes.
• Thermoplastic Material: Longer-chain polyoxymethylenes, also known as polyoxymethylene plastics (POM, Delrin), are used in various applications.
• Crosslinking Agents: Paraformaldehyde is used in techniques like ChIP (chromatin immunoprecipitation) to study protein-DNA interactions. Buy factory price Paraformaldehyde/ CAS NO. 30525-89-4 wholesale.

Paraformaldehyde must be depolymerized into formaldehyde to act as a fixative. In cell culture, a 4% formaldehyde solution in phosphate-buffered saline (PBS) is typically used on ice for 10 minutes. For histology and pathology, a 10% Neutral Buffered Formalin (4% formaldehyde) solution is used for at least 24 hours. Buy factory price Paraformaldehyde/ CAS NO. 30525-89-4 wholesale. Paraformaldehyde can also replace aqueous formaldehyde in producing resinous binding materials, often combined with melamine, phenol, or other reactive agents in the production of particle board, medium-density fiberboard, and plywood.
