2-Nitrochlorobenzene is an organic compound with the formula ClC 6 H 4 NO 2. It is one of three isomeric nitrochlorobenzenes . [ 1 ] It is a yellow crystalline solid that is important as a precursor to other compounds due to its two functional groups.

In the U.S., under the Food, Drug, and Cosmetic Act and the Fair Packaging and Labeling Act, certain accurate information is a requirement to appear on labels of cosmetic products. [6] In Canada, the regulatory guideline is the Cosmetic Regulations. [7] Ingredient names must comply by law with EU requirements by using INCI names. [8]
Castor oil and its derivatives are found in many cosmetics as it is "non-comedogenic" (does not exacerbate or contribute to acne). [3]Cerebrosides (cells from the nervous systems of cattle or swine) were once used in some high-end skin-care products to increase moisture retention and to create a smooth skin surface, [4] however the BSE controversy has put an end to this practice.
[1] [2] Titanium dioxide (TiO 2) and zinc oxide (ZnO) minerals are often utilized in sunscreens as inorganic physical sun blockers owing to their absorption of light in the UV range. As TiO 2 is proven to be more effective for blocking UVB and ZnO in the UVA range, the mix of these particles guarantees a broad-band UV shield. [3]
Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3-nitrochlorobenzene. Since the above synthetic route does not efficiently produce the 3-isomer, the route most commonly used by chemists is the chlorination of nitrobenzene .
Instead, the main product he isolated was chlorobenzene. [5] In modern times, the Sandmeyer reaction refers to any method for substitution of an aromatic amino group via preparation of its diazonium salt followed by its displacement with a nucleophile in the presence of catalytic copper(I) salts.
Cosmetics products may be retailed in beauty stores, department stores and hypermarkets, drugstores, variety stores, grocery stores, beauty supply stores, and many other formats, and in similar types of online stores or the online presence of these types of physical stores.
