52429-99-9 Usage
Purification Methods
Purify it by recrystallisation from dimethylformamide. The purity is checked by paper chromatography, RF 0.90 [i-PrOH/saturated (NH4)2SO4/H2O, 2:79:19 as eluent], IR (KBr) 16201570 ( C=C, C=N) and max 1253 (P=) cm-1.[Takaku et al. ull Chem Soc Jpn 47 779 1974.]
Check Digit Verification of cas no
The CAS Registry Mumber 52429-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,4,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52429-99:
(7*5)+(6*2)+(5*4)+(4*2)+(3*9)+(2*9)+(1*9)=129
129 % 10 = 9
So 52429-99-9 is a valid CAS Registry Number.

Lead ion induced chemodosimeter approach of a tripodal hydroxyl-quinoline based phospho-ester through P-O bond cleavage

Lead ion induced P-O bond breaking with instant colour change was observed in a tripodal hydroxyl-quinoline based phosphor-ester (HQP). A new penta-coordinated lead chelate complex [Pb4HQ6(ClO4)2] was found. The hydrolysis reaction followed by P-O bond cleavage with 'Pb-O' and 'Pb-N' bond formation proved the chemodosimeter approach.
