590-28-3 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 590-28-3 differently. You can refer to the following data:
1. Potassium cyanate, KOCN,is colorless,water soluble crystals. Used as an herbicide and for the manufacture of drugs and organic chemicals,
2. Potassium cyanate, KCNO, white solid, soluble, formed along with lead metal by reaction of potassium cyanide and lead monoxide solids upon heating. Source of cyanate.

Uses

Different sources of media describe the Uses of 590-28-3 differently. You can refer to the following data:
1. Potassium cyanate is used as an inhibitor to prevent sickling of erythrocytes and has potential use as a treatment for sickle-cell anemia. Potassium cyanate is also used as a reagent to carbamylate proteins.
2. Herbicide, manufacture of organic chemicals and drugs, treatment of sickle-cell anemia.
3. Potassium cyanate is used as chemical intermediate and as a weed killer. It is also used for the heat treatment of metals.

General Description

Potassium cyanate can be prepared by reacting urea with alkali hydroxide or carbonates at high temperatures.

Flammability and Explosibility

Notclassified

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. Causes irritation of the gastrointestinal tract. An herbicide. It is said to be slowly metabolized in the body to cyanide but does not have high toxicity of cyanides. When heated to decomposition it emits very toxic fumes of CNand K2O.

Purification Methods

Common impurities include ammonia and bicarbonate ion (from hydrolysis). Purify it by preparing a saturated aqueous solution at 50o, neutralising with acetic acid, filtering, adding two volumes of EtOH and keeping for 3-4hours in an ice bath. (More EtOH can lead to co-precipitation of KHCO3.) Filter, wash it with EtOH and dry it rapidly in a vacuum desiccator (P2O5). The process is repeated [Vanderzee & Meyers J Chem Soc 65 153 1961].

Check Digit Verification of cas no

The CAS Registry Mumber 590-28-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 590-28:
(5*5)+(4*9)+(3*0)+(2*2)+(1*8)=73
73 % 10 = 3
So 590-28-3 is a valid CAS Registry Number.

3D coordination polymer of copper (II)-potassium (I): Crystal structure and thermal decomposition kinetics

Shen, Xiao-Qing,Qiao, Hai-Bin,Li, Zhong-Jun,Zhang, Hong-Yun,Liu, Hong-Lei,Yang, Rui,Chen, Pei-Kun,Hou, Hong-Wei

, p. 642 - 648 (2006)

A new heterometallacrown coordination polymer [K2Cu(NPA) 2(H2O)4]n (where H2NPA = 3-nitro-phthalic acid) has been synthesized and it's crystal structure has been elucidated. In the complex, the o-phthalate group coordinates to metal atoms behaving as both tetradentate and heptadentate coordination, the modes of which have been found for the first time. The thermal behaviors of this complex and the thermal decomposition kinetics have been studied. Kinetic analysis shows that the decomposition of title complex in the main range acts as two separate transitions with the first one being a double-step following reaction, A→F1B→FnC, and the second being a three-step following reaction of t:f,f, A→F2B→F2C→R2D. The kinetic parameters of these processes were also obtained.

Development of metal cyanurates: The example of barium cyanurate (BCY)

Kalmutzki, Markus,Str?bele, Markus,Bettinger, Holger F.,Meyer, H.-Jürgen

, p. 2536 - 2543 (2014)

Metal cyanurate compounds were prepared by means of solid-state metathesis reactions between a metal halide and an alkali cyanurate. Following this procedure, a mixture of BaCl2 and K(OCN) was heated in a fused silica tube at 575 C to yield highly crystalline barium cyanurate. This reaction was analyzed by differential scanning calorimetry (DSC) measurements and involves a cyclotrimerization of cyanate ions to yield the cyclic cyanurate (O 3C3N3)3- ion. The crystal structure of Ba3(O3C3N3)2 was refined by single-crystal X-ray diffraction, and the presence of cyanurate was verified by infrared spectroscopy.

Catalyst + chemodosimeter → chemosensor: Incorporation of catalytic functionality in an indicator displacement assay to realize reversible chemosensing detection

Chow, Cheuk-Fai,Gong, Cheng-Bin,Shen, Chang,Tang, Qian

, p. 5029 - 5035 (2020)

A new bimetallic complex, (CN)3FeII(tppz)CuIICl (tppz = 2,3,5,6-tetra(2′-pyridyl)pyrazine) including an Fe(ii)-diimine indicator and a dual functional Cu(ii) receptor/catalyst, was synthesized to demonstrate the concept of indicator/catalyst displacement assay for the simultaneous detection and detoxification of cyanide. The catalytic degradation property in the assay was necessary for making the detecting system reversible, which the traditional indicator displacement assays could never achieve. After the realization of this new property, silica-gel-based solid-supporting complex 1 was fabricated for application in a device, which was demonstrated for its use in the naked-eye detection and degradation of cyanide in tap, river, and underground water samples in a repeatable and real-time manner, even in the presence of interfering anions (CH3COO-, N3-, HCO3-, Cl-, NO3-, HPO42-, SO42-, SCN-, and OCN-). Within 300 min, cyanide was quantitatively oxidized into the less toxic cyanate by 1 in the presence of H2O2. The detection limit of 1 for cyanide was found to be 1.16 × 10-4 M (3.02 mg L-1).
