Sah, Peter P. T. published the artcilep-Iodobenzohydrazide as a reagent for the identification of aldehydes and ketones, Safety of 4-Iodobenzohydrazide, the publication is Recueil des Travaux Chimiques des Pays-Bas et de la Belgique (1940), 349-56, database is CAplus.

cf. C. A. 29, 466.2; 30, 2875.6. p-Iodobenzohydrazide is prepared as follows: 3 g. p-IC6H4CO2Me and 4 cc. of N2H4.H2O (40%) are boiled while 4 cc. of absolute alc. are added. After refluxing for 8 hrs. and cooling, the hydrazide seps. and may be recrystallized from 50% alc. Yield 2.7 g., m. 168-9° (corrected). The following compounds gave hydrazones with the indicated corrected m. p.: AcH 224°, EtCHO 196°, PrCHO 201°, iso-PrCHO 209-10°, BuCHO 152°, iso-BuCHO 218-19°, AmCHO 148-9°, iso-AmCHO 171-2°, heptaldehyde 190-1°, octaldehyde 155°, nonylaldehyde 135-6°, decylaldehyde 151-2°, acetone 214-15°, MeCOEt 164-5°, Me hexyl ketone 125-6°, BzH 237-8°, benzylideneacetone 229-30° (decomposition), 2-furaldehyde 235° (decomposition), acetophenone 212°, p-methylacetophenone 214°, p-ethylacetophenone 167-8°, AcCH2CO2Et 107-9°, levulinic acid 184-5°, Me levulinate 163-4°, Et levulinate 127-8°, benzylideneacetophenone 182°, salicylaldehyde 214-15°, p-hydroxybenzaldehyde 295-6° (decomposition), cyclohexanone 188-9°, camphor 153-4°, citral 99-100°, fenchone 168-9°. The m. ps. of the hydrazones differ sufficiently to make identification possible without the use of mixed m. ps. and for that reason this reagent is recommended as a substitute for 2,4-dinitrophenylhydrazine and semicarbazide. The yields of the hydrazones are so high that 300 mg. of the reagent are sufficient.
