The asymmetric unit of the title compound, 2C(10)H(11)N(5)O·C(6)H(10)O(4), consists of a 2,4-diamino-6-(4-meth-oxy-phen-yl)-1,3,5-triazine mol-ecule and one-half mol-ecule of adipic acid which lies about an inversion center. The triazine ring makes a dihedral angle of 12.89 (4)° with the adjacent benzene ring. In the crystal, the components are linked by N-H⋯O and O-H⋯N hydrogen bonds, thus gen...

In the title mol-ecule, C(12)H(12)N(4)O(3)S, there is an intra-molecular O-H⋯N hydrogen bond. The dihedral angle between the benzene and triazine rings is 65.9 (3)°. In the crystal, N-H⋯S and O-H⋯N hydrogen bonds link the mol-ecules into chains along [010]. In addition, there are weak π-π stacking inter-actions between symmetry-related triazine rings with a centroid-centroid distance of 3.560 (...

Cell-free extracts of Rhodococcus corallinus NRRL B-15444R dechlorinated deethylsimazine (2-chloro-4-ethylamino-l,3,5-triazine-6-amine) to N-ethylammeline (2-amino-4-ethylamino-l,3,5-triazine-6(SH)-one) anaerobically, and, thus, presumably hydrolytically. Two enzyme fractions (M, about 450000 and 180000) that dechlorinated deethylsimazine were detected after gel permeation chromatography of cel...

A blue-fluorescence 2,4,6-tris(4-fluorophenyl)-1,3,5-triazine (TFPT) monomer was synthesized with high yield and high purity under mild reaction conditions. The TFPT, which had three active fluoric groups, was facilely incorporated into stable cross-linked fluorescent polymeric nanoparticles (FCPNs) via precipitation polymerization with 6-(4-hydroxyphenyl)pyridazin-3(2H)-one (HPZ). The FCPNs we...

A traceless solid-phase synthesis of 6-amino- and 6-hydroxyimino-1,3,5-triazine-2,4-diones and 1,3,5-triazine-2,4,6-triones has been developed. The strategy comprises of linking a preformed N-carbamothioylcarbamate to bromomethyl resin to give a S-linked isothiourea, which then undergoes cyclization with isocynates to yield the resin-bound 1,3,5-triazine-2,4-diones. Subsequent cleavage was acco...

Photopolymerization has attracted great interest because of its mild reaction conditions, spatiotemporal controllability, cost efficiency, and fast speed. However, with the raising environmental awareness increasing attention to life health, leachability photoinitiators become a growing concern. In this research, methacrylate functionalized triazine-based polymerizable visible light photoinitia...

The s-triazine cyclopropylmelamine (N-cyclopropyl-1,3,5-triazine-2,4,6-triamine) was degraded to about 6 mol of NH4+/mol of substrate by a mixture of two bacteria (strains A and D, both Pseudomonas spp.) Only strain A grew with cyclopropylmelamine as sole and limiting source of nitrogen. The organism obtained 2 mol of nitrogen/mol of substrate and excreted a product that was identified as cyclo...

The NCNN group is an essential part of various heterocycles bearing high biological activities. 1,2,4-Triazines and their condensed derivatives found applications as pharmaceuticals and in agriculture. For example vardenafil ñ phosphodiesterase inhibitor, is useful in the treatment of male erectile dysfunctions (1), apazone exhibit anti-inflammatory and analgesic actions (2), lamotrigine is use...
