505-54-4 Usage

Uses

Hexadecanedioic Acid is a useful research intermediate for the studies of blood pressure regulations in humans. Hexadecandedioate works in collaboration with SLCO1B1 as a potential therapy for statin.

Chemical Properties

white powder

Definition

ChEBI: An alpha,omega-dicarboxylic acid that is the 1,14-dicarboxy derivative of tetradecane.

Purification Methods

Crystallise thaspic acid from EtOH, ethyl acetate or *C6H6. [Beilstein 2 IV 2162.]

Check Digit Verification of cas no

The CAS Registry Mumber 505-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 505-54:
(5*5)+(4*0)+(3*5)+(2*5)+(1*4)=54
54 % 10 = 4
So 505-54-4 is a valid CAS Registry Number.

Preparation method of long-chain diacid

-

, (2021/11/03)

The invention provides a preparation method of long-chain diacid, which comprises the following steps of: (S1) carrying out an addition reaction on olefine acid or an ester derivative thereof serving as a raw material and liquid bromine to obtain dibromo carboxylic acid or an ester derivative thereof; (S2) carrying out an elimination reaction on the dibromo carboxylic acid or ester derivative thereof under the action of sodium amide to obtain alkynyl-terminated carboxylic acid or an ester derivative thereof; (S3) carrying out an addition reaction on the alkynyl-terminated carboxylic acid or the ester derivative thereof and diborane to obtain borane or boric acid containing carboxyl or ester group; and (S4) oxidizing the borane or boric acid to obtain long-chain diacid. According to the invention, olefine acid is used as a raw material, is easily available in source and low in price, so that the production cost of the product is very low; and meanwhile, the raw materials used in the synthesis process do not contain precious metals or other expensive reagents, so that the synthesis process is suitable for industrial amplification production, and the defect that the method in the prior art is not environment-friendly, not suitable for industrial production and high in preparation cost is overcome.

Paragraph 0094; 0109-0116; 0126; 0142-0149; 0159; 0175-0182, (2021/06/13)

The invention relates to a preparation method of long-chain alkyl diacid mono-tert-butyl ester, belonging to the technical field of organic synthesis. According to the invention, long-chain alkyl diacid is used as an initial raw material and reacts with oxalyl chloride to generate long-chain monoacyl chloride, and the long-chain monoacyl chloride and tert-butyl alcohol are subjected to an esterification reaction to generate the long-chain alkyl diacid mono-tert-butyl ester. According to the invention, a novel synthesis route is adopted, and raw material cost is reduced; and the method has the characteristics of mild reaction conditions, simple process operation, high product purity, high production efficiency and the like, and has good application prospects.
