The title compound, C(14)H(10)ClN(3)O(4)·CH(4)O, was synthesized from the reaction of 5-chloro-salicylaldehyde with 4-nitro-benzohydrazide in methanol. The Schiff base mol-ecule is nearly planar, with a dihedral angle of 9.1 (3)° between the two benzene rings. The methanol solvent mol-ecules are linked to the Schiff base mol-ecules by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming chains running parallel to the a axis.

A novel fluorescence sensing nanoplatform (CDs/AuNCs@ZIF-8) encapsulating carbon dots (CDs) and gold nanoclusters (AuNCs) within a zeolitic imidazolate framework-8 (ZIF-8) was developed for ratiometric detection of formaldehyde (FA) in the medium of hydroxylamine hydrochloride (NHOH·HCl). The nanoplatform exhibited pink fluorescence due to the aggregation-induced emission (AIE) effect of AuNCs and the internal filtration effect (IFE) between AuNCs and CDs. Upon reaction between NHOH·HCl and FA, a Schiff base formed via aldehyde-diamine condensation, releasing hydrochloric acid.

Background: Synthesis of the original Schiff base CdCl (CHNO) compound (Schiff base complex) displays an extensive range of bioactivities and was predictably utilized to treat several syndromes.
Purpose: The goal of the existing experiment is to evaluate the gastroprotective effects of a novel Schiff base CdCl₂ (C14H21N3O2) compound in alcohol-induced gastric ulcers in rats by examining its antioxidant activity, anti-inflammatory effects, and modulation of key molecular markers, including heat shock protein-70 (HSP-70) and Bcl-2-associated X protein (Bax) proteins.
Methods: Five groups of rats were utilized in the current study.

Solid-state synthesis is an approach to organic synthesis that is desirable because it can offer minimal or no solvent waste, high yields, and relatively low energy footprints. Herein, we report the solid-state synthesis of a novel Schiff base, 4-{()-[(4-methylpyridin-3-yl)imino]methyl}benzoic acid (), synthesized through the reaction of an amine and an aldehyde. was prepared via solvent-drop (water) grinding (SDG) on a multigram scale with 97% yield and was characterized using FTIR, H NMR, and SCXRD.
