Melting Point : 65-67° C (lit.) Boiling Point : 297-298° C (lit.)
A secondary alcohol that is diphenylmethane which carries a hydroxy group at position 1. Diphenylmethanol is the organic compound with the formula (C6H5)2CHOH. Also known as benzhydrol, it is a white solid and the parent member of a large class of diaryl alcohols.
3. Chemical and physical properties of the pure substance. Solubility: Practically insoluble in water, but soluble in organic solvents such as alcohol, acetone, ether, acetic acid, chloroform and benzene. Stability: Decomposes on heating to produce toxic gases; reacts with strong oxidants.
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Diphenylmethanol is the organic compound with the formula (C6H5)2CHOH. Also known as benzhydrol, it is a white solid and the parent member of a large class of diaryl alcohols.
Benzhydrol is widely used as intermediates in pharmaceuticals (including antihistamines), agrochemicals, perfumes and other organic compounds. It is used as a fixative in the perfume industry. It is involved in polymerization reaction as a terminating group.

|Melting point||48.5 °C (119.3 °F; 321.6 K)|
|Boiling point||305.4 °C (581.7 °F; 578.5 K)|
|Solubility in water||Insoluble|
Benzhydrol contains an alcohol functional group. It is attached to the two phenyl rings. So, it has the polar character due to the alcoholic functional group but the non-polar part is also there as two benzene rings are present.
Safety Information In addition, a Cosmetic Ingredient Review (CIR) expert scientific panel states that benzophenone and its derivatives (benzophenone-1, -3, -4, -5, -9 and -11) are safe as typically used in cosmetics and personal care products.
Methanol has an intermediate polarity; however, it can dissolve benzophenone because the polar carbonyl group on benzophenone can make hydrogen bond to the methanol; therefore, making benzophenone soluble in methanol.

Benzophenone occurs naturally in some foods (such as wine grapes and muscat grapes) and is added to other foods as a flavoring. In personal care products, benzophenone is used as a fragrance enhancer or to prevent products such as soaps from losing scents and colors in the presence of UV light.
The benzophenone is activated by UV light to an extremely reactive triplet-state ketone, which can insert into CH, NH, and other structures, resulting in a covalent bond (Chapter 3, Section 7.2).

Notably, we propose (S)-aziridinyl diphenylmethanol as a promising CSA, which has excellent chiral discriminating properties and offers multiple detectable possibilities pertaining to the 1H NMR signals of diagnostic split protons (including 25 examples, up to 0.194 ppm, 77.6 Hz).
CONSIDERED A HAZARDOUS SUBSTANCE ACCORDING TO OSHA 29 CFR 1910.1200. May cause SENSITISATION by skin contact. Irritating to eyes, respiratory system and skin. The material has NOT been classified as “harmful by ingestion”.
The answer is of course an hydroxyl substituent, a strongly POLAR functional group; i.e. (H5C6)2CH(OH) versus O=C(C6H5)2 .
* Breathing Sodium Borohydride can irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. * Very high exposure to Sodium Borohydride may affect the nervous system.
The Diphenylmethanol molecule contains a total of 27 bond(s) There are 15 non-H bond(s), 12 multiple bond(s), 2 rotatable bond(s), 12 aromatic bond(s), 2 six-membered ring(s), 1 hydroxyl group(s) and 1 secondary alcohol(s).
The solubility of benzophenone in various pure solvents, including water, ethanol, 1-propanol, isopropanol, methanol, 1-butanol, isobutanol, 1-octanol, acetonitrile, acetone, ethyl acetate, and methyl acetate, has been measured at temperatures between 278.15 and 318.15 K by a gravimetric method under atmospheric …
Since benzophenone can further delocalize this positive charge into its phenyl groups, the conjugate acid of benzophenone is the most stabilized of the three acids, leading to benzophenone being the strongest base.
Benzophenone is the simplest member of the class of benzophenones, being formaldehyde in which both hydrogens are replaced by phenyl groups. It has a role as a photosensitizing agent and a plant metabolite. Benzophenone is the organic compound.
The methylene group in diphenylmethane is mildly acidic with a pKa of 32.2, and so can be deprotonated with sodium amide.
Biphenyl appears as a clear colorless liquid with a pleasant odor. Flash point 180°F. Insoluble in water.
Yes, in all cases, Sun Bum follows the recommendations and guidelines set by the Skin Cancer Foundation (SCF), the American Cancer Society (ACS), and the FDA. Sun Bum sunscreens are stringently tested, approved, and recommended by the SCF. …
Is Benzene the Same Thing as Oxybenzone? No benzene is not the same thing as oxybenzone. In fact, Oxybenzone is a completely separate, incredibly common active ingredient found in chemical sunscreens, which are different, from zinc or titanium-based mineral sunscreens.
There’s no evidence that sunscreen is bad for you. Though a small 2020 FDA study found that the body can absorb some chemicals for certain sunscreens, it hasn’t been proven that it has any adverse health effects.
