2,4-DNP
2,4-DNP (Product Code: SCL-742/116) is an analytical reagent in a 100 gm pack used for organic chemistry practical work in school and college laboratories. In practical lists the abbreviation most often stands for 2,4-dinitrophenylhydrazine, the reagent that detects the carbonyl group in aldehydes and ketones, but the same letters are also used for 2,4-dinitrophenol, so please confirm the compound your syllabus needs when you enquire. It is supplied with its MSDS by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is 2,4-DNP Used For?
Where 2,4-DNP means 2,4-dinitrophenylhydrazine, it is used in the classic carbonyl test. The teacher first makes up a working reagent solution following the lab manual; students then add a few drops of the test compound, for example an aldehyde such as benzaldehyde or a ketone such as acetone, to a portion of that solution in a test tube. A yellow, orange or red precipitate shows that a carbonyl group is present, while alcohols and carboxylic acids do not give it. In college laboratories the precipitate can be filtered, recrystallised and its melting point used to help identify the original aldehyde or ketone.
Dry dinitro compounds can be sensitive to heat, friction and shock, so keep the container closed, away from flames and hot plates, and let only staff handle the solid. The reagent stains skin and clothing, so gloves and eye protection are sensible even for small-scale tests. Schools that buy from a single chemistry consumables supplier in India often order it with the test compounds and glassware listed below, so one delivery covers the whole practical.
Supplier
Jain Scientific Equipments Private Limited trades as ScienceLab from Ambala, Haryana, India, and supplies chemicals and reagents such as this one to schools, colleges and dealers in India and international markets.

Related Chemistry Lab Equipment
A carbonyl-group practical needs known compounds to test and basic bench equipment. These items are often ordered with it:
- Benzaldehyde — an aromatic aldehyde that gives a positive carbonyl result.
- Acetone — a simple ketone for comparison with the aldehyde.
- Test Tube Racks — hold a row of tubes while students compare results.
- Functional Group Chart — links each observation to the group responsible.
- Safety Goggles — eye protection while reagents are handled.

Frequently Asked Questions
Which compound is sold as 2,4-DNP?
The product is listed under the abbreviation 2,4-DNP. In school practicals this usually means 2,4-dinitrophenylhydrazine for the carbonyl test, but the abbreviation is also used for 2,4-dinitrophenol, so please confirm the compound you need through our contact page before ordering.
What pack size and grade is 2,4-DNP?
2,4-DNP is supplied in a 100 gm pack and is listed as an analytical reagent. Give the number of packs and the exact compound you need when you enquire, so the quotation matches your practical list.
Is a safety data sheet included with 2,4-DNP?
Yes. 2,4-DNP is supplied with an MSDS (Material Safety Data Sheet). Read it before first use, keep it with your chemical stock register, and follow its storage and handling advice for this dinitro compound.
What is the shelf life of 2,4-DNP?
Shelf life depends on the chemical, its grade and storage conditions, so no single expiry period is given for 2,4-DNP. Ask us for the expiry date of the batch you are quoted, and keep it tightly closed in a cool, dry place away from heat and light.
Can students use 2,4-DNP solid directly?
No. For the carbonyl test, 2,4-DNP solid is normally made into a reagent solution by the teacher, following the lab manual, and students work only with that prepared solution under supervision, wearing gloves and eye protection.
Who supplies 2,4-DNP?
2,4-DNP is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and dealers in India and international markets. Shipping arrangements for chemicals are confirmed order by order, so share the quantity and destination when you enquire.
