General Description

Colorless crystalline solid.

Reactivity Profile

Propham is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Hazard

Toxic by ingestion.

Health Hazard

Moderately toxic herbicide; exhibited low tomoderate toxicity in experimental animalswhen administered by oral, intraperitoneal,intravenous, and subcutaneous routes; skinabsorption is slow; cholinesterase inhibitor;in human ingestion can cause carbamatepoisoning, which can be lethal when takenin large amount; probable lethal oral dosein adult human estimated to be larger thanother carbamate insecticides within the range35–50 g.

Safety Profile

Poison by intraperitoneal route. Moderately toxic to humans by ingestion. Moderately toxic experimentally by ingestion and possibly other routes. An experimental teratogen. Human mutation data reported. Questionable carcinogen with experimental neoplastigenic data. An herbicide. When heated to decomposition it emits toxic fumes of NO,. See also CARBAMATES.

Potential Exposure

A potential danger to those involved in the manufacture, formulation and application of this car- bamate/organonitrogen grass-control herbicide.

Environmental Fate

Biological. Rajagopal et al. (1989) reported that Achromobacter sp. and an Arthrobacter sp. utilized propham as a sole carbon source. Metabolites identified were Nphenylcarbamic acid, aniline, catechol, monoisopropyl carbonate, 2-propanol and carbon dioxide (Rajagopal et al., 1989). Soil. Readily degraded by soil microorganisms forming aniline and carbon dioxide (Humburg et al., 1989). The reported half-life in soil is approximately 15 and 5 days at 16 and 29°C, respectively (Hartley and Kidd, 1987). Groundwater. According to the U.S. EPA (1986) propham has a high potential to leach to groundwater. Plant. The major plant metabolite which was identified from soybean plants is isopropyl N-2-hydroxycarbanilate (Hartley and Kidd, 1987; Humburg et al., 1989). Chemical/Physical. Hydrolysis of propham yields N-phenylcarbamic acid and 2-propanol. The acid is very unstable and is spontaneously decomposed to form aniline and carbon dioxide (Still and Herrett, 1976). Emits toxic fumes of nitrogen oxides when heated to decomposition (Sax and Lewis, 1987).

Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. In accordance with 40CFR165, follow recom- mendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following pack- age label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.

Check Digit Verification of cas no

The CAS Registry Mumber 122-42-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122-42:
(5*1)+(4*2)+(3*2)+(2*4)+(1*2)=29
29 % 10 = 9
So 122-42-9 is a valid CAS Registry Number.

Indirect reduction of CO2and recycling of polymers by manganese-catalyzed transfer hydrogenation of amides, carbamates, urea derivatives, and polyurethanes

Liu, Xin,Werner, Thomas

, p. 10590 - 10597 (2021/08/20)

The reduction of polar bonds, in particular carbonyl groups, is of fundamental importance in organic chemistry and biology. Herein, we report a manganese pincer complex as a versatile catalyst for the transfer hydrogenation of amides, carbamates, urea derivatives, and even polyurethanes leading to the corresponding alcohols, amines, and methanol as products. Since these compound classes can be prepared using CO2as a C1 building block the reported reaction represents an approach to the indirect reduction of CO2. Notably, these are the first examples on the reduction of carbamates and urea derivatives as well as on the C-N bond cleavage in amides by transfer hydrogenation. The general applicability of this methodology is highlighted by the successful reduction of 12 urea derivatives, 26 carbamates and 11 amides. The corresponding amines, alcohols and methanol were obtained in good to excellent yields up to 97%. Furthermore, polyurethanes were successfully converted which represents a viable strategy towards a circular economy. Based on control experiments and the observed intermediates a feasible mechanism is proposed.

An Fe3O4@SiO2/Schiff base/Cu(ii) complex as an efficient recyclable magnetic nanocatalyst for selective mono: N-arylation of primary O-alkyl thiocarbamates and primary O-alkyl carbamates with aryl halides and arylboronic acids

Sardarian, Ali Reza,Dindarloo Inaloo, Iman,Zangiabadi, Milad

, p. 8557 - 8565 (2019/06/14)

An efficient, convenient and novel method for the selective mono N-arylation of primary O-alkyl thiocarbamates and primary O-alkyl carbamates with aryl halides and arylboronic acids in the presence of a recyclable magnetic Cu(ii) nanocatalyst is described. A variety of mono N-arylated O-alkyl thiocarbamates and O-alkyl carbamates were prepared in good to excellent yields with a broad range of aryl coupling partners. The magnetic nanocatalyst can be easily recovered with an external magnetic field and reused at least five times without noticeable leaching or loss of its catalytic activity. This cost-effective and eco-friendly methodology has some other advantages, such as easy preparation of the catalyst, simple workup procedure, and easy purification, which makes this protocol interesting for the users in various fields of pharmacology and biotechnology systems.
