چکیده
In the title compound, C(13)H(10)N(+)·C(7)H(5)O(3) (-) or (acrH)(+)(Hsal)(-), the asymmetric unit contains one acridinium cation and one salicylate anion. The acridinium N atom is protonated and the carb-oxy-lic acid group of salicylic acid is deprotonated. Both moieties are planar, with an r.m.s. deviation of 0.0127 Å for the acr cation and 0.0235 ° for the sal anion. They are aligned with a dihedral angle of 71.68 (3)° between them. The crystal structure is stabilized by a network of inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. C-H⋯π inter-actions are also present.

The N-H⋯O hy...
متن کاملSynthesis and properties of differently charged chemiluminescent acridinium ester labels.
Chemiluminescent acridinium dimethylphenyl esters containing N-sulfopropyl groups in the acridinium ring are highly sensitive, hydrophilic labels that are used in automated immunoassays for clinical diagnostics. Light emission from these labels is triggered with alkaline peroxide in the presence of a cationic surfactant. At physiological pH, N-sulfopropyl acridinium esters exist as water adduct...
متن کاملChemiluminescence from alkoxy-substituted acridinium dimethylphenyl ester labels.
Chemiluminescent acridinium dimethylphenyl ester labels are used in automated immunoassays for clinical diagnostics. Light emission from these labels is triggered by alkaline peroxide in the presence of the cationic surfactant cetyltrimethylammonium chloride (CTAC). The surfactant plays a critical role in the chemiluminescence process of these labels by both accelerating their emission kinetics...
متن کاملA comparison of chemiluminescent acridinium dimethylphenyl ester labels with different conjugation sites.
Chemiluminescent acridinium dimethylphenyl esters are highly sensitive labels that are used in automated assays for clinical diagnosis. Light emission from these labels and their conjugates is triggered by treatment with alkaline peroxide. Conjugation of acridinium ester labels is normally done at the phenol. During the chemiluminescent reaction of these acridinium esters, the phenolic ester is...
متن کاملSynthesis and properties of chemiluminescent acridinium ester labels with fluorous tags.
Acridinium dimethylphenyl esters are highly sensitive chemiluminescent labels that are used in clinical diagnostics. Light emission from these labels is triggered with alkaline peroxide in the presence of the cationic surfactant cetyltrimethylammonium chloride (CTAC). CTAC compresses emission times of these labels to <5 seconds and also increases overall light yield 3-4 fold. The observed enhan...
