▶Sodium Nitrite

7632-00-0

Sodium nitrite ( Na₂NO₂ ) is commonly used for coloring and preserving fish, meat , and other foods. Pure sodium nitrite is a white to pale yellow crystal. It has excellent water solubility and hygroscopicity ; its aqueous solution is weakly alkaline with a pH of approximately 9. It is readily soluble in liquid ammonia and slightly soluble in organic solvents such as ethanol , methanol , and ether . In air, sodium nitrite is slowly oxidized to sodium nitrate ( Na₂NO₃ ), which is a strong oxidizing agent . Sodium nitrite is prone to explosion upon contact with organic matter.

▶Potassium Nitrate

7757-79-1

Saltpeter, also known as potassium nitrate , is typically a colorless crystal or white powder. It is odorless but has a cooling sensation. It is a nitrogen- and potassium-containing compound fertilizer and a strong oxidizing agent used in the manufacture of gunpowder, fireworks, and glass, as well as as a food preservative and toothpaste desensitizer. It is readily soluble in water but must be stored away from flammable materials and reducing agents. It is flammable and poses a risk of combustion and explosion upon contact with organic matter.

▶N-Heptane

142-82-5

N-heptane is an organic compound with chemical formula C7H16. It is a colorless, transparent and volatile liquid. It is insoluble in water, soluble in ethanol and carbon tetrachloride, and miscible in ether, chloroform, acetone and benzene. It is mainly used as a standard and solvent for octane number determination, and can also be used for organic synthesis and preparation of experimental reagents.

▶Potassium Formate

590-29-4

An organic salt, usually a white solid, highly hygroscopic, non-toxic and non-corrosive, primarily used in oil drilling fluids (as an environmentally friendly drilling fluid additive), and also as an environmentally friendly de-icing agent, leather industry auxiliary agent, electroplating additive, carbon black surface modifier, and agricultural foliar fertilizer. It is readily soluble in water, its aqueous solution is colorless, it has reducing properties, and it can react with strong oxidizing agents.

▶Magnesium Acetate

142-72-3

It is commonly found as white crystals or powder, readily soluble in water, and has a slightly acetic acid-like aroma. It is an important chemical, used as an analytical reagent (e.g., for sodium determination), a catalyst, a pharmaceutical raw material, and a feed additive, usually existing in tetrahydrate form.

▶Citric Acid Monohydrate

5949-29-1

Citric acid monohydrate is a form of citric acid that contains one molecule of water in its crystal structure, making it a white crystalline powder or granules, naturally found in citrus fruits, and widely used as an acidulant, flavoring, preservative, and pH adjuster in food, drinks, cosmetics, and medicine. It's essentially the same as anhydrous citric acid once dissolved in water, differing only in its crystalline form, with the water molecule being easily lost upon heating.

▶Potassium acid citrate tripotassium citrate anhydrous

866-84-2/7778-49-6

Potassium citrate is a salt of citrate with the molecular formula K3C6H5O7. It is a white, slightly hygroscopic crystalline powder. It is odorless and has a saline taste.

▶Poly(vinyl chloride) PVC Resin powder

9002-86-2/93050-82-9

PVC resin has a wide range of applications and can be used in the production and processing of PVC hard products, soft products, coatings, and adhesives.
