74038-47-4 Usage

General Description

1-Hydroxy-2-methylpropylphosphonic acid diethyl ester, also known as ethephon, is an organophosphorus compound commonly used as a plant growth regulator and ripening agent for fruits such as bananas and tomatoes. It works by releasing ethylene gas, which stimulates the ripening process in plants and promotes fruit maturation. Ethephon is also used in agriculture to control flowering and fruit set in various crops, and as a defoliant in cotton and other crops. Due to its potential to cause skin and eye irritation, as well as environmental concerns, its use is regulated in many countries.

Check Digit Verification of cas no

The CAS Registry Mumber 74038-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,3 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74038-47:
(7*7)+(6*4)+(5*0)+(4*3)+(3*8)+(2*4)+(1*7)=124
124 % 10 = 4
So 74038-47-4 is a valid CAS Registry Number.

The preparation of dialkyl 1-hydroxyalkylphosphonates in the reaction of trialkyl phosphites with oxonium salts derived from aldehydes or ketones

Goldeman, Waldemar,Soroka, Miroslaw

, p. 3019 - 3024 (2006)

The reaction of trialkyl phosphites with aldehydes or ketones in the presence of hydrogen chloride gives dialkyl 1-hydroxyalkylphosphonates via Arbusov-like reaction of oxonium salts derived from aldehydes or ketones. This reaction is a very convenient instant method for the preparation of dialkyl 1-hydroxyalkylphosphonates with a good yield as an alternative to the well-known Abramov reaction.
