However, a major breakthrough in the development of the TDR mechanism came with the improved understanding of the phenomenon behind amine groups reacting with nitrous acid.

The bottom figure shows the survival curves for inactivation of phage T4 by the DNA damaging agent methyl methane sulfonate ( MMS ) and nitrous acid.

Meticulous kinetic studies throughout the late 1950s led scientists to believe that nitrous acid reacts with an amine by first producing a nitrous acid derivative, potentially N2O3.

In this synthesis, the methyl anthranilate successively reacts with nitrous acid ( from sodium nitrite and hydrochloric acid ), sulfur dioxide, chlorine, and then ammonia to yield saccharin:

Oxidation with nitrous acid then produces the azo compound "'4 "'from which on heating above the melting point, nitrogen gas evolves with formation of tetraphenylmethane "'5 " '.

Nitrous acid is used to make diazides from amines; this occurs by nucleophilic attack of the amine onto the nitrite, reprotonation by the surrounding solvent, and double-elimination of water.
28.
Nitrogen is the most common gas in the atmosphere and several active nitrogen compounds, including nitrous acid, can damage the ozone themselves, said Konrad Mauersberger of the Max Planck Institute.
29.
The unusual alkyl nitrite starting material of the Barton reaction is prepared by attack of an alcohol on a nitrosylium cation generated in situ by dehydration of doubly protonated nitrous acid.
30.
Base on the fact that dilute nitrous acid can oxidize iodide into iodine, it can be deduced that nitrous is a faster, rather than a more powerful, oxidizing agent than dilute nitric acid.
