930-08-5 Usage
General Description
3,6,9,12-Tetraoxapentacosan-1-ol, also known as triacontanol, is a fatty alcohol that is found in plant waxes and cuticles. It is a long-chain primary alcohol with a 30-carbon backbone and four oxygen atoms in its structure. Triacontanol is known for its plant growth-promoting properties and has been shown to increase the yield and quality of crops when applied in small concentrations. It also has potential applications in the pharmaceutical and cosmetic industries due to its high melting point and emulsifying properties. Triacontanol has also been investigated for its potential as a biofuel and as a precursor for the synthesis of other organic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 930-08-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 930-08:
(5*9)+(4*3)+(3*0)+(2*0)+(1*8)=65
65 % 10 = 5
So 930-08-5 is a valid CAS Registry Number.

Combinatorial synthesis of PEG oligomer libraries

Page/Page column 9, (2010/02/15)
A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.
