156-87-6 Usage

Chemical Properties

clear colourless to very slightly yellow liquid

Uses

Different sources of media describe the Uses of 156-87-6 differently. You can refer to the following data:
1. Organic intermediate.
2. 3-Amino-1-propanol is used in the production of anionic emulsifiers, nonionic polyethylene emulsions. Its salts such as hydrochloride, nitrate, sulfate, phosphate are used for the balanced curing action with selected textile resins. It is used as a starting material in the preparation of beta-lactam antibiotics, humectants for foods and cosmetics. It acts as a corrosion inhibitor and finds application in water treatment, metal treatment and absorption of carbon dioxide gas.
3. 3-Amino-1-propanol was used in the synthesis of di-tert-butyl aminopropanol derivative.

General Description

Colorless to pale yellow liquid with a fishy odor. Less dense than water. Melting point 12.4°C (54°F). Moderately toxic by ingestion.

Air & Water Reactions

Water soluble.

Reactivity Profile

3-Aminopropanol neutralizes acids to form salts plus water in an exothermic reaction. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Reacts with strong reducing agents, such as hydrides to generate flammable gaseous hydrogen.

Hazard

Irritant to tissue.

Health Hazard

If inhaled may be harmful. Contact may cause burns to skin and eyes. (Organic base.)

Flammability and Explosibility

Nonflammable

Safety Profile

Moderately toxic by ingestion and skin contact. An experimental teratogen. A severe skin and eye irritant. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.

Check Digit Verification of cas no

The CAS Registry Mumber 156-87-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156-87:
(5*1)+(4*5)+(3*6)+(2*8)+(1*7)=66
66 % 10 = 6
So 156-87-6 is a valid CAS Registry Number.

Paragraph 0040; 0042; 0043; 0045; 0046; 0048; 0049; 0051, (2020/05/05)

The invention relates to a preparation method of 3-aminopropanol, wherein the preparation method comprises the following steps: (1) carrying out a reaction on acrylonitrile with benzyl alcohol under the catalysis of a base catalyst, and separating the obtained reaction solution to obtain 3-benzyloxypropionitrile; and (2) in a liquid-phase reaction system in the presence of a hydrogenation catalyst, carrying out a hydrogenation reaction on the 3-benzyloxypropionitrile, separating the obtained reaction liquid to obtain 3-aminopropanol, and recycling the obtained by-product toluene as an extractant in the step (1).

Oxidative Deprotection of p-Methoxybenzyl Ethers via Metal-Free Photoredox Catalysis

Ahn, Deok Kyun,Kang, Young Woo,Woo, Sang Kook

, p. 3612 - 3623 (2019/03/11)

An efficient and greener deprotection method for p-methoxybenzyl (PMB) ethers using a metal-free visible light photoredox catalyst and air and ammonium persulfate as the terminal oxidants is presented. Various functional groups and protecting groups were tolerated in the developed method to achieve good to excellent yields in short reaction times. Significantly, the developed method was compatible with PMB ethers derived from primary, secondary, and tertiary alcohols and a gram-scale reaction. Mechanistic studies support a proposed reaction mechanism that involves single electron oxidation of the PMB ether.
