16672-87-0 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 16672-87-0 differently. You can refer to the following data:
1. white to beige powder
2. Ethephon is a white to tan powder. Commercial
product is a white, waxy solid. Commercial products may be
available as aqueous solutions or soluble concentrates.
Uses
Different sources of media describe the Uses of 16672-87-0 differently. You can refer to the following data:
1. 2-Chloroethyl)phosphonic acid (Ethephon) is the most widely used plant growth regulator. Ethephon is often used on wheat, coffee, tobacco, cotton, and rice in order to help the plant's fruit reach mat
urity more quickly. The toxicity of Ethephon is actually very low, and any Ethephon used on the plant is converted very quickly to ethylene.
2. Plant growth regulator.
3. Accelerates the preharvest ripening of fruits and vegetables.
Definition
ChEBI: A phosphonic acid compound having a 2-chloroethyl substituent attached to the P-atom.
Agricultural Uses
Plant growth regulator: Ethephon is a plant growth regulator used to promote
fruit ripening, abscission, flower induction, and other responses.
It is registered for use on a number of food, feed
and nonfood crops (rubber plants, flax), greenhouse nursery
stock, and outdoor residential ornamental plants, but is used
primarily on cotton. Ethephon is applied to plant foliage by
either ground or aerial equipment. It also may be applied
by hand sprayer to certain home garden vegetables and ornamentals.
Use practice limitations include prohibitions
against applying ethephon through any type of irrigation system;
feeding or grazing livestock in treated areas; and treating
within 2 to 60 days of harvest, depending on the crop.

Safety Profile
Moderately toxic by
ingestion. Mddly toxic by skin contact. A
plant growth regulator. Caution: Spray
formulations are quite acidic, about pH 1 .O.
May be irritating to exposed skin and eyes,
or if inhaled. When heated to
decomposition it emits toxic fumes of Cl
and POx.
Potential Exposure
Ethephon is an organophosphonate
plant growth regulator used to promote fruit ripening,
abscission, flower induction, and other responses. It is registered for use on a number of food, animal feed and nonfood
crops (rubber plants, flax), greenhouse nursery stock, and
outdoor residential ornamental plants, but is used primarily
on cotton. Ethephon is applied to plant foliage by either
ground or aerial equipment. It also may be applied by hand
sprayer to certain home garden vegetables and ornamentals.
Use practice limitations include prohibitions against applying ethephon through any type of irrigation system; feeding
or grazing livestock in treated areas; and treating within
2 to 60 days of harvest, depending on the crop
Environmental Fate
Soil. Degrades rapidly in soil to phosphoric acid, ethylene and chloride ions (Hartley
and Kidd, 1987) and naturally occurring substances (Humburg et al., 1989).
Chemical/Physical. In an aqueous solution at pH 3.5, ethepon begins to hydrolyze,
releasing ethylene (Windholz et al., 1983).
Shipping
UN2928 Toxic solids, corrosive, organic, n.o.s.,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials,
8-Corrosive material, Technical Name Required
Incompatibilities
Hygroscopic. Aqueous solutions are
highly acidic. May cause corrosion if metals, especially
when moisture is present. Contact with flammable material
may cause fire and explosions. Contact with combustible or
oxidizable materials may form heat-, shock-, and frictionsensitive explosive mixtures. Static electricity may also
cause explosions. Keep away from all acids, especially
dibasic organic acids, ammonium compounds, antimony
sulfide, arsenic trioxide, metal sulfides, powdered metals,
calcium aluminum hydride, cyanides, manganese dioxide,
phosphorus, selenium, sulfur, thiocyanates, and zinc.
Waste Disposal
Destruction by alkali hydrolysis or incineration. Containers must be disposed of properly
by following package 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 16672-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,7 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16672-87:
(7*1)+(6*6)+(5*6)+(4*7)+(3*2)+(2*8)+(1*7)=130
130 % 10 = 0
So 16672-87-0 is a valid CAS Registry Number.

Joint production method of ethephon and vinylphosphonic acid
-
Paragraph 0015, (2018/02/04)
The invention discloses a joint production method of ethephon and vinylphosphonic acid. The joint production method comprises the following steps of acylating bis(2-chloroethyl)-2-chloroethyl phosphonate by phosgene or thionyl chloride under the action of a catalyst to obtain a mixture of vinyl phosphonic chloride and 2-chloroethyl phosphonic chloride; separating the vinyl phosphonic chloride from the 2-chloroethyl phosphonic chloride in a reduced pressure distillation mode; hydrolyzing the vinyl phosphonic chloride and the 2-chloroethyl phosphonic chloride to obtain the vinylphosphonic acid and the ethephon. According to the joint production method disclosed by the invention, two products of the ethephon and the vinylphosphonic acid are synthesized by using the bis(2-chloroethyl)-2-chloroethyl phosphonate; a process is simple, and the purities of the two products are improved.
Preparation of high quality ethephon using domestic diester bis-(2-chloroethyl)-2-chloroethylphosphonate as substrate
Zhang, Wenlong,Sun, Dequn
, p. 6463 - 6464 (2013/07/26)
Ethephon has been widely used globally. However, few companies can manufacture high quality ethephon with content of 90% in China mainland. This work described a practical procedure, which utilizing bis-(2-chloroethyl)-2- chloroethylphosphonate 2 produced by local Chinese companies as substrate to prepare ethephon with content of over 90 % and high yield.
