1-Heptyne is used in the chemical industry as an intermediate in the synthesis of various organic compounds. It is particularly used in the synthesis of two specific compounds: (6Z,10E,12Z)-octadeca-6,10,12-trienoic acid and (8Z,12E,14Z)-eicosa-8,12,14-trienoic acid.
Used in Chemical Synthesis:
1-Heptyne is used as a starting material for the synthesis of (6Z,10E,12Z)-octadeca-6,10,12-trienoic acid, which is an unsaturated fatty acid with three double bonds. 1-Heptyne has potential applications in the pharmaceutical and cosmetic industries due to its biological properties.
1-Heptyne is also used as a precursor in the synthesis of (8Z,12E,14Z)-eicosa-8,12,14-trienoic acid, another unsaturated fatty acid with three double bonds. 1-Heptyne may have potential applications in various industries, such as the production of specialty chemicals, pharmaceuticals, and nutraceuticals.
Check Digit Verification of cas no
The CAS Registry Mumber 628-71-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 628-71:
(5*6)+(4*2)+(3*8)+(2*7)+(1*1)=77
77 % 10 = 7
So 628-71-7 is a valid CAS Registry Number.

Paragraph 0026; 0053; 0054, (2018/05/01)
The invention discloses an efficient synthesis method of methyl dihydrojasmonate. Under catalysis of homogeneous rhodium and organic nitric oxide, 1-heptyne and ethylene have Pauson-Khand reaction, 2-amyl-2-cyclopentenone is rapidly and efficiently obtained, and an intermediate is subjected to addition and decarboxylation by dimethyl malonate to obtain the methyl dihydrojasmonate. The efficient synthesis method mainly has the advantages that 1-heptyne and ethylene Pauson-Khand reaction yield is effectively improved by the aid of the organic nitric oxide, and usage of rhodium catalysts is reduced. Compared with a traditional methyl dihydrojasmonate production method, the method has the advantages that route steps are short, atom economy is high, the cost is low, and the method is suitable for scale production of the methyl dihydrojasmonate.
