2-Formyl-3-hydroxy-9,10-anthroquinone
The mol-ecule of the title compound, C(15)H(8)O(4), is approximately planar. An intra-molecular O-H⋯O hydrogen bond is observed between the hydr-oxy and formyl groups. The crystal used was a nonmerohedral twin, with a minor twin component of 15.9%.
متن کاملMineralization of the dibenzothiophene biodegradation products 3-hydroxy-2-formyl benzothiophene and dibenzothiophene sulfone.
Dibenzothiophene is degraded to 3-hydroxy-2-formyl benzothiophene by various bacteria, including a strain of Pseudomonas putida that also forms dibenzothiophene sulfone via an alternate pathway. By using these end products as substrates, mixed enrichment cultures that could degrade 3-hydroxy-2-formyl benzothiophene and dibenzothiophene sulfone with the formation of CO2 were established.

A large-scale field experiment was used to test whether exposure to a suite of potential environmental factors (flow speed, temperature, salinity, and low dissolved oxygen) influences the level of parasitic infection of the oyster Crassostrea virginica. The parasite was the protozoan Perkinsus marinus, which has decimated populations of oysters in estuaries of North America. The environmental f...
متن کامل(E)-Methyl 2-[(2-formyl-6-methoxyphenoxy)methyl]-3-phenylacrylate
The title compound, C(19)H(18)O(5), crystallizes with two independent mol-ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis-ectional orientation as evidenced by the dihedral angle between them [41.7 (1)° in mol-ecule A and 35.6 (1)° in mol-ecule B]. Both mol-ecules adopt an E configuration with respect to the C=C bond. An intra-molecular C-H⋯O hydrogen-...
متن کامل4-Formyl-2-nitrophenyl 3-nitro-2-methylbenzoate
In the title formyl nitro aryl benzoate derivative, C15H10N2O7, the benzene rings form a dihedral angle of 4.96 (3)°. The mean plane of the central ester group, C-O-C-(=O)-C (r.m.s. deviation = 0.0484 Å), is twisted away from the formyl nitro aryl and benzoate rings by 46.61 (5) and 49.93 (5)°, respectively. In the crystal, the mol-ecules are packed forming C-H⋯O inter-actions in chains which p...
