9051-49-4 Usage
Uses
Pentaerythritol propoxylate may be used as a precipitant in reservoir solution for the crystallization of Phosphate Transporter(PiPT) and Aggregation Suppressing Protein A(AgsA). It may also acts as a reservoir solution for Phytosulfokine (PSK)- receptor PSKR- and somatic embryogenesis receptor-like kinases (SERKs) complex.
Definition
ChEBI: A hydroxypolyether in which a hydroxy-poly(propylene oxide) chain is connected to each of the methyl groups of neopentane. It is commonly used to crystallise proteins. In the diagram, a + b + c + d ~ 5.
General Description
Pentaerythritol propoxylate (5/4 PO/OH) is a pentaerythriol based branched polymer that can be used as a crystallization agent to generate ordered, high resolution diffraction quality crystals.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 9051-49-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 9051-49:
(6*9)+(5*0)+(4*5)+(3*1)+(2*4)+(1*9)=94
94 % 10 = 4
So 9051-49-4 is a valid CAS Registry Number.
