Acetic acid-(3-fluoro-[2]pyridyl ester) is a chemical compound that can be described as an ester derivative of acetic acid, where the hydroxyl group of acetic acid is replaced by a 3-fluoro-[2]pyridyl group. This fluorinated pyridine moiety introduces a fluorine atom at the 3-position of the pyridine ring, which is attached to the acetic acid through an ester linkage. The compound is characterized by its molecular structure that combines the properties of acetic acid with the electronic and steric effects of the fluorinated pyridine ring. It is a white crystalline solid and is used in various chemical reactions and as an intermediate in the synthesis of pharmaceuticals and agrochemicals. The presence of the fluorine atom can significantly alter the reactivity and physical properties of the molecule, making it a valuable building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 2267-37-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,6 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2267-37:
(6*2)+(5*2)+(4*6)+(3*7)+(2*3)+(1*7)=80
80 % 10 = 0
So 2267-37-0 is a valid CAS Registry Number.

Utilizing Acetyl Hypofluorite for Chlorination, Bromination, and Etherification of the Pyridine System

Hebel, David,Rozen, Shlomo

, p. 6298 - 6301 (2007/10/02)

Acetyl hypofluorite, which is easily made from F2, possesses a strong electrophilic fluorine.This electrophile is able to attach itself to the nitrogen atom of pyridine and activate the ring toward nucleophilic attacks.The ultimate elimination of HF results in an overall easy nucleophilic displacement of the hydrogen of the important 2-position .The nucleophiles used: Clδ-, Brδ-, ROδ-, originate from solvents such as CH2Cl2, CH2Br2, and various primary alcohols.Thus, 2-halo- or 2-alkoxypyridines were formed.The reaction conditions (room temperature, very short reaction times, and good yields) transform the task of direct substitution of the pyridine ring from an extremely difficult to a very easy procedure.
