“…In the title mol­ecule, C(13)H(14)N(2)O(2), the dihedral angle between the pyrazole and benzene ring mean planes is 76.06 (11)°, and the conformation of the ethyl side chain is anti [C—O—C—C = −175.4 (3)°]. In the crystal, the only directional inter­actions are very weak C—H ⋯π inter­actions involving both the pyrazole and benzene rings, leading to the formation of a three-dimensional network.…”

“…In the title compound, C(8)H(7)ClFNO, the F atom is disordred over the meta positions of the benzene ring in a 0.574 (4):0.426 (4) ratio and the Cl atom is syn to the O atom [O—C—C—Cl = 5.6 (3)°]. A short intra­molecular C—H⋯O contact occurs. …”

“…We have studied the cyclodehydration step using acetic anhydride, trifluoroacetic anhydride and 1,3-dicyclohexyl-carbodiimide (DCC) at temperatures not exceding 60(o)C. Trifluroacetic anhydride proved to be the best reagent, giving a better yield and more easily purified products, although yields were also acceptable with the other two reagents.…”

“…The protocol described below explains the preparation of a fixative combination saline (FCS) formulation, which allows fixation of human WBCs and lysis of red blood cells and platelets (at ambient temperature, 4–35(o)C) in whole blood samples in one step. FCS can be used for storing and transporting blood at ambient temperatures for up to 4 months, without altering the nuclear morphology and genomic integrity of WBCs.…”
