General Description

4-Methoxypicolinaldehyde, also known simply as 4-MOPA, is a chemical compound commonly used in the field of chemistry, specifically in organic synthesis. It has the molecular formula C7H7NO2 and is known for its aromatic quality, signifying that it contains a stabilised ring of atoms which makes it chemically robust. 4-Methoxypicolinaldehyde plays a significant role as a building block in the synthesis of various pharmaceuticals and bioactive compounds. In its standard state, it appears as a clear yellow to brownish liquid and must be handled carefully, in a well-ventilated area, due to the potential health risks associated with contact and inhalation.

Check Digit Verification of cas no

The CAS Registry Mumber 16744-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,4 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16744-81:
(7*1)+(6*6)+(5*7)+(4*4)+(3*4)+(2*8)+(1*1)=123
123 % 10 = 3
So 16744-81-3 is a valid CAS Registry Number.

Design of coordination interaction of Zn(II) complex with oligo-aspartate peptide to afford a high-affinity tag-probe pair

A complementary recognition pair consisting of a genetically encodable peptide tag and a small molecular probe isa powerful tool to specifically label and manipulate a protein ofinterest under biological conditions. In this study, we report the redesign of a tag-probe pair comprising an oligo-aspartate peptide tag (such as DDDD) and a binuclear zinc complex. Isothermal-titration calorimetry screening of binding between the series of peptides and zinc complexes revealed that the binding affinity was largely influenced by subtle changes of the ligand structure of the probe. However, the binding was tolerant to differences of the tag peptide sequence. Of those tested, a pair containing a peptide tag (DDAADD) and a binuclear zinc complex possessing 4-chloropyridines (3-2Zn(II)) showed the strongest binding affinity (Ka = 3.88 × 105 M-1), which was about 10-fold larger than the conventional pair of D4-peptide tag (DDDD) and 1-2Zn(II) containing nonsubstituted pyridines (Ka = 3.73 × 104 M-1). The strong binding of this new complementary recognition pair enabled the rapid covalent labeling of a tag-fused maltose binding protein with a fluorescent zinc complex, demonstrating its potential utility in protein analysis.
