Spectrophotometric Determination of Amoxicillin Using New Organic Reagent via Different Analytical Methods

open access: yesIndonesian Journal of Chemistry, 2023
New and simple spectrophotometric method was applied for amoxicillin determination by oxidative coupling with an organic reagent 1-(4-aminophenyl)-3-(5-(4-nitrophenyl)-furan-2-yl)-yl)-prop-2-en-1-one (H) to form an orange colored dye with λmax of 490 nm.

The “Coefficients H” Technique [PDF]

open access: yes, 2009
The "coefficient H technique" is a tool introduced in 1991 and used to prove various pseudo-random properties from the distribution of the number of keys that sends cleartext on some ciphertext. It can also be used to find attacks on cryptographic designs. We can like this unify a lot of various pseudo-random results obtained by different authors.
