Reagent

Reagent (pronounced ree-ey-juhnt)

In chemistry, a substance that produces a chemical reaction, used in analysis and synthesis.

1785: A compound word, the construct being re(act)- + agent.  The prefix re- is from the Middle English re-, from the Old French re-, from the Latin re- & red- (back; anew; again; against), from the primitive Indo-European wret-, a metathetic alteration of wert- (to turn).  Agent is from the Latin agēns, present active participle of agere (to drive, lead, conduct, manage, perform, do) from the Proto-Italic agō, from primitive Indo-European hzéǵeti.  It was cognate with the Old Irish aigid, the Ancient Greek ἄγω (ágō) (I lead), the Old Norse aka (move, drive), the Avestan azaiti and the Sanskrit अजति (ájati) (to drive, propel, cast).

The difference between a catalyst and a reagent is that catalysts are not consumed during the chemical reaction, whereas reagents may be.  A catalyst is a substance which can increase the reaction rate of a particular chemical reaction, while a reagent is a substance used in chemical analysis or to induce another chemical reaction.

Novichok

A Novichok (Russian: новичо́к (novičók) (newcomer)) agent is one of a number of chemical weapons developed by the state chemical research institute (GosNIIOKhT) in the Soviet Union (USSR) and Russia between 1971-1993.  Said to be the deadliest nerve agent ever created, Novichok was designed in a way that evaded the restrictions on chemical weapons imposed by treaties to which the USSR was a signatory.  Novichok agents have become well-known because they’ve been used to poison several opponents of the Russian government, most notably Sergei Skripal (b 1951; a former officer in the Russian military agent of UK intelligence) and his daughter, Yulia Skripal (b 1985) who were poisoned in the city of Salisbury, UK.  The Kremlin denied complicity and accused the UK government of whipping-up anti-Russian hysteria.

The design requirements for Novichok included it being undetectable using standard equipment, being able to penetrate personal protective equipment, being easier to handle in its transportable form and able to circumvent the various chemical weapons treaties the USSR had signed.  The use of reagents made many of these objectives possible.  As a binary weapon, in which precursors are mixed to produce the nerve agent immediately prior use, handling is easier because, in un-mixed form, the reagents are less hazardous and thus simpler to store and transport.  The reagents are also chemically less unstable and have a long shelf life although western analysts note at least one liquid form of Novichok is sufficiently stable to be able to remain deadly for decades if stored in a controlled environment.

In July 2018, a UK distillery was forced to apologize after releasing a 75% abv vodka named Novichok, days after a woman and her partner were poisoned with the same nerve agent that almost killed Sergei Skripal and his daughter Yulia in Salisbury earlier in the year.  Bristol Dry Gin’s limited edition Novichok vodka quickly sold out and the company has made clear there are no plans for a second batch.  Amesbury woman Dawn Sturgess (b 1974), who lived some eight miles (13 km) north of Salisbury, fell ill on 30 June 2018, dying within days after being exposed to what experts said must have been a sizable dose of the Novichok substance.  Her partner, Charlie Rowley (b 1973), was for some time critically ill but recovered.

Just before Ms Sturgess’ death, Bristol Dry Gin posted to its Facebook page an image of its new “limited edition” Novichok vodka, along with a promotional blurb: "Our new limited edition vodka is out! Set at 75%, this smooth drinking spirit is no laughing matter."  "Available as a 35cl bottle, perfect for manbags and gym bottles, or as a pack of three 5cl minis, a great solution to body cavity searches. Get em from our web store or distillery.”  Not so much the product as the timing of the release attracted criticism, many finding it in “poor taste” and the distillery in its statement of apology agreed, admitting the timing “may have lacked sensitivity” and was named and launched only after the Skripals had recovered.  “It was intended to lighten the mood and ease tensions, not to cause offence, and reaction has been overwhelmingly positive. We sincerely apologize if any offence was caused, especially to the families of Dawn Sturgess and Charlie Rowley, and understand the timing of the release of this product may have lacked sensitivity.  The Novichok Edition is a limited edition, which sold out within a hours of being released, and we have no plans to produce any more.”

Capitalism in Russia proved a little more robust, a Russian entrepreneur capitalizing on the poisoning in the UK of Sergei & Yulia Skripala by releasing the новичо́к (novičók or Novichok) brand of cooking oil.  Ulyanovsk-based farmer Alexei Yakushev explained he was inspired to choose the name for his new brand of sunflower oil after watching a news report of the events in Salisbury.  “I regularly watch the news” Mr Yakushev informed an interviewer and as the product wasn’t available in store, he decided to produce and bring it to market himself.

Said to be the ideal oil for sukhariki (oven-toasted stale bread strips), the Novichok oil was marketed under the slogan “products for a long life” and, in a nice touch, the label included the famous insignia of the KGB.  On Mr Yakushev’s webpage, to counter Western propaganda, he included in the “About us” section the line “We don’t hide money offshore,” in rhyme.
