Description
3-S-Isothiuronium propyl sulfonate (UPS) is a white crystalline powder with unique chemical properties that make it useful in various applications.
Uses
Used in Electroplating Industry:
3-S-Isothiuronium propyl sulfonate is used as a stabilizer and accelerator for EN deposition. At lower concentrations, it effectively enhances the deposition process, while at higher concentrations, it reduces the deposition rate. Additionally, UPS decreases the phosphorus content in Ni-P deposits and can be adsorbed on the deposit surface, forming compounds with Ni2+.
Used in Proteomics Research:
3-S-Isothiuronium propyl sulfonate is used as a component of the Proteomics Dynamic Range Standard Set, which is designed to standardize and evaluate mass spectrometric and electrophoretic analysis conditions before analyzing complex protein samples. UPS2 serves as an external reference to help laboratories generate or compare mass spectrometric data derived from poorly defined samples, ensuring the robustness of the analysis method and the stability of the instrument used. Furthermore, it has been utilized for the quantification of dynamic range universal protein standard on Orbitrap Analyzer using all ion fragmentation and as a standard for intensity-based absolute quantification of proteins (iBAQ) in LC-MS/MS analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 21668-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,6 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21668-81:
(7*2)+(6*1)+(5*6)+(4*6)+(3*8)+(2*8)+(1*1)=115
115 % 10 = 5
So 21668-81-5 is a valid CAS Registry Number.
