Amperometric Determination of Tin with Cupferron

open access: yesAnalytical Chemistry, 1959
Distillation of tin tetrabromide followed by an amperometric titration with cupferron is specific for the determination of tin(IV). Because large amounts of bromide and chloride interfere with the amperometric titration the tin in the distillate is precipitated with ammonia using an aluminum hydroxide carrier.

Structure of Mandelate Racemase with Bound Intermediate Analogues Benzohydroxamate and Cupferron

open access: yes, 2016
Mandelate racemase (MR, EC 5.1.2.2) from Pseudomonas putida catalyzes the Mg2+-dependent interconversion of the enantiomers of mandelate, stabilizing the altered substrate in the transition state by 26 kcal/mol relative to the substrate in the ground ...

ROT RESISTANCE OF COTTON DUCK TREATED WITH CHELATE COPPER COMPOUNDS

open access: yes, 1948
Thirteen organic compounds capable of forming chelate complexes were used to fix copper in cotton duck. Their rotproofing effectiveness was then determined by the loss in tensile strength during soil burial.
