The present invention relates to a novel compound, to a composition comprising the same, to methods for preparing the compound, and the use of this compound in therapy. In particular, the present invention relates to a compound that is useful in the treatment and prevention of primary and secondary arterial hypertension, ictus, myocardial ischaemia, cardiac and renal insufficiency, myocardial infarction, peripheral vascular disease, diabetic proteinuria, Syndrome X and glaucoma.

The invention is a herbicidal composition containing an alkanolamine salt of an dicamba capable of remaining as a single phase liquid over a period of at least 1 week and containing low amounts of water and high loadings of the salt. Such herbicidal compositions are capable of remaining liquid in the absence of high amounts of water, thereby enhancing their capacity to remain liquid over an extended period of time when exposed to environmental conditions to improve their effectiveness to transport the active salt through a leafy substrate and can reduce transportation costs by increasing the salt loading without compromising the stability of the composition.

The present disclosure is directed to a crystal of L-glufosinate and a preparation method and use thereof. The crystal of L-glufosinate includes five crystal forms, namely crystal form A, crystal form B, crystal form C, crystal form D and crystal form E. These crystal forms show excellent effects in stability, hygroscopicity, storage, etc., which are beneficial to the preparation, separation and storage of herbicides, and at the same time have good solubility and good pharmacokinetics, which is further beneficial to improve the level and speed of herbicides to control weeds.

Provided are a method for preparing L-glufosinate and the intermediate compounds of formula (V) and formula (III).

The present invention relates primarily to processes conducted in a continuously operated reactor for preparing particular phosphorus-containing α-aminonitriles of the formulae (Ia) and (Ib) defined hereinafter from corresponding phosphorus-containing cyanohydrin esters and to the use thereof for preparation of glufosinate or of glufosinate salts. The present invention further relates to a process for producing glufosinate/glufosinate salts.

Preparation of phosphorus fine chemicals from phosphate sources is described.

The present invention relates primarily to a process for preparing certain phosphorus-containing cyanohydrins of the formula (I), and also to certain phosphorus-containing cyanohydrins per se and to their use for the preparation of glufosinate and/or glufosinate salts. The present invention further relates to certain mixtures particularly suitable for preparing the phosphorus-containing cyanohydrins of the formula (I).

The present disclosure is drawn to a photo active agent which includes a bisacylphosphinic compound in the form of an acid or salt having Structure I: where A and A are independently aryl or from C2 to C8 lower alkyl; M is H, a monovalent cation, a divalent cation, or mixture thereof; n is 1 or 2; and q is 1 or 2. The photo active agent can be present in a composition that includes from 0.001 wt % to 5 wt % of a dialcohol phosphinic acid precursor or dialcohol phosphinic salt of the bisacylphosphinic compound of Structure I. ##STR00001##

The present invention relates primarily to processes for preparing particular phosphorus-containing -aminonitriles of the formulae (Ia) and (Ib) defined hereinafter from corresponding phosphorus-containing cyanohydrin esters and to the use thereof for preparation of glufosinate or of glufosinate salts. The present invention further relates to a process for preparing glufosinate or glufosinate salts.

The invention relates to agriculture, and specifically to regulators of plant growth and development that can be used for the pre-sowing treatment of cereal crop seeds and are in the form of bis(oxymethyl)phosphinic acid and biogenic metal salts thereof with the general formula (I) Me.sup.n+[OP(O)(CH.sub.2OH).sub.2].sub.n, where n may be 1 or 2 and Me may be any of the following: H, Na, Ca, Mg, Co, Cu, Zn, Mn. The claimed compounds of formula I are effective regulators of plant growth and development when acting in concentrations of 1.Math.10.sup.7-1.Math.10.sup.12%. Pre-sowing treatment of the seeds of cereal crops, namely wheat, corn and rice, by means of the claimed compounds increases germination energy and germination capacity up to 13%, also increases plant vigor, and rootlet and shoot lengths increase up to 36%. Crop harvests increase and the quality of the resulting grain improves, which expands the range of effective, environmentally friendly plant growth and development regulators that act at the level of natural phytohormones.
