Description
Different sources of media describe the Description of 112-86-7 differently. You can refer to the following data:
1. Erucic acid also known as cis-13-Docosenoic acid is a monounsaturated omega-9 fatty acid. It occurs at high concentrations mainly in the seeds of species of the Brassicaceae (e.g. rape seed or mustard seed, and seeds from vegetable crops such as kales, cabbages and turnips).
High-erucic acid oils are used either directly as lubricants (e.g. in the manufacture of rubber additives) or in formulations. They are used as spinning lubricants in the textile, steel, and shipping industries; as cutting, metal-forming, rolling, fabricating, and drilling oils; and as marine lubes. Erucic acid can also be oxidatively cleaved to brassylic acid for use in the production of polyesters. The oxidative cleavage of erucic acid can be performed via ozonolysis or by reaction with hydrogen peroxide in the presence of an inorganic oxide catalyst. Erucic acid can be used to prepare useful nitrogen derivatives: behenyl amine is used in a corrosion inhibitor; disubstituted amides are effective plasticizers and erucamide is an excellent slip and antiblocking agent for plastic films.
2. Erucic acid is a monounsaturated omega-9 fatty acid, denoted 22:1ω9. It has the formula CH3(CH2)7CH=CH(CH2)11COOH. It is prevalent in wallflower seed, makes up 4.1% of rapeseed oil, and makes up 42% of mustard oil. Erucic acid is also known as cis-13- docosenoic acid and the trans isomer is known as brassidic acid.

Uses
Different sources of media describe the Uses of 112-86-7 differently. You can refer to the following data:
1. 13(Z)-Docosenoic acid is a 22-carbon monounsaturated fatty acid. It is found predominantly in canola oil. 13(Z)-Docosenoic acid is metabolized to oleic acid in vivo. Diets rich in 13(Z)-docosenoic acid were shown to cause heart lipidosis in experimental animals. The C-1 amide of docosenoic acid has been identified as one of the anandamide-related neurotransmitters associated with sleep.
2. Erucic acid has many of the same uses as mineral oils, but it is more readily biodegradable than some. It has limited ability to polymerize and dry for use in oil paints. Like other fatty acids, it can be converted into surfactants or lubricants, and can be used as a precursor to bio-diesel fuel. Derivatives of erucic acid have many further uses, such as behenyl alcohol ( CH3(CH2)21OH ) , a pour point depressant (enabling liquids to flow at a lower temperature), and silver behenate, for use in photography. It is also used as an ingredient in appetite suppressants.
3. Erucic acid is a long-chain alcohol that acts as an inhibitor of fatty acid oxidation in the heart. Erucic acid originates in rapeseed plants, and is the major fatty acid constituent of rapeseed plant oil extracts and canola oil.
Definition
ChEBI: A docosenoic acid having a cis- double bond at C-13. It is found particularly in brassicas - it is a major component of mustard and rapeseed oils and is produced by broccoli, Brussels sprouts, kale, and wallflowers.
Biotechnological Applications
Erucic acid is produced by elongation of oleic acid via oleoylcoenzyme A and malonyl- CoA. Erucic acid is broken down into shorter- chain fatty acids in the human liver by the long - chain Acyl CoA dehydrogenase enzyme.
Purification Methods
Crystallise erucic acid from MeOH. [Beilstein 2 IV 1676.]
Check Digit Verification of cas no
The CAS Registry Mumber 112-86-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 112-86:
(5*1)+(4*1)+(3*2)+(2*8)+(1*6)=37
37 % 10 = 7
So 112-86-7 is a valid CAS Registry Number.

Biotechnological strategies using renewable materials as starting substrates are a promising alternative to traditional oleochemical processes for the isolation of different fatty acids. Among them, long chain mono-unsaturated fatty acids are especially interesting in industrial lipid modification, since they are precursors of several economically relevant products, including detergents, plastics and lubricants. Therefore, the aim of this study was to develop an enzymatic method in order to increase the percentage of long chain mono-unsaturated fatty acids from Camelina and Crambe oil ethyl ester derivatives, by using selective lipases. Specifically, the focus was on the enrichment of gondoic (C20:1 cisΔ11) and erucic acid (C22:1 cisΔ13) from Camelina and Crambe oil derivatives, respectively. The pursuit of this goal entailed several steps, including: (i) the choice of a suitable lipase scaffold to serve as a protein engineering template (Candida antarctica lipase A); (ii) the identification of potential amino acid targets to disrupt the binding tunnel at the adequate location; (iii) the design, creation and high-throughput screening of lipase mutant libraries; (iv) the study of the selectivity towards different chain length p-nitrophenyl fatty acid esters of the best hits found, as well as the analysis of the contribution of each amino acid change and the outcome of combining several of the aforementioned residue alterations and, finally, (v) the selection and application of the most promising candidates for the fatty acid enrichment biocatalysis. As a result, enrichment of C22:1 from Crambe ethyl esters was achieved either, in the free fatty acid fraction (wt, 78%) or in the esterified fraction (variants V1, 77%; V9, 78% and V19, 74%). Concerning the enrichment of C20:1 when Camelina oil ethyl esters were used as substrate, the best variant was the single mutant V290W, which doubled its content in the esterified fraction from approximately 15% to 34%. A moderately lower increase was achieved by V9 and its two derived triple mutant variants V19 and V20 (27%). (Figure presented.).
