O jẹ agbo-ara Organic pẹlu agbekalẹ kemikali ti C. H brn₂. Atẹle ni apejuwe ti iseda rẹ, lilo, agbekalẹ ati alaye ailewu:

 

Iseda:

-Irisi: Colorless kirisita ri to

-Solubility: Soluble ni Organic solvents bi ethanol ati dimethylformamide

-Melting Point: nipa 84-86 ℃

-Molecular iwuwo: 203.05g/mol

 

Lo:

-G le ṣee lo bi awọn agbedemeji ati awọn reagents ni iṣelọpọ Organic.

-O le ṣee lo lati ṣajọpọ awọn agbo ogun Organic gẹgẹbi awọn oogun, awọn awọ awọ ati awọn ipakokoropaeku pẹlu awọn ẹya bii imidazole ati pyridine.

 

Ọna:

- Ọpọlọpọ awọn ọna ti iṣelọpọ, eyiti o le gba nipasẹ ọkan ninu awọn ọna wọnyi:

1. Idahun ti 2-cyano -5-bromomethyl -1-methyl pyridine ati cyanogen bromide

2. Fesi 2-cyanopyridine pẹlu methoamine ati methyl bromide

3. Idahun ti 2-bromopyridine pẹlu carbonitrile ati hydrocyanic acid

 

Alaye Abo:

- jẹ ẹya Organic yellow pẹlu awọn majele ti.

Nigbagbogbo wọ awọn ohun elo aabo ti ara ẹni ti o yẹ gẹgẹbi awọn ibọwọ, awọn gilaasi ati awọn aṣọ laabu nigba mimu ati lilo.

-Yago fun ifasimu, jijẹ tabi fifọwọkan awọ ara lati yago fun majele.

- Tọju ati lo ni agbegbe ailewu, yago fun olubasọrọ pẹlu oxidants ati awọn combustibles.
