Succinic Anhydride

CAS No.: 108-30-5
Grades: White Grade and Yellow Grade
Standard net weight: 25 kg per bag
20ft container capacity: 20 metric tons

Succinic Anhydride, CAS 108-30-5, is offered in two grades so buyers do not pay for whiteness they do not need. The White Grade is white to off-white crystals and flakes at 99.5% min purity for pharmaceutical and food additive work; the Yellow Grade is light yellow to yellow flakes at 98.0% min purity for industrial synthesis where colour is not a critical factor. Both deliver the reactivity expected of a key intermediate in organic synthesis, and both are packed in sealed inner bags at 25 kg net.

Why buyers specify this grade

Two grades from one supplier, so the colour specification is matched to the end product instead of over-bought
Yellow Grade purity is still controlled at 98.0% min, so reaction efficiency is not traded away for price
White Grade at 99.5% min purity meets premium pharmaceutical and food additive requirements
Moisture-proof sealed polyethylene inner bag inside a kraft paper or plastic outer bag
Container capacity is fixed and known: 20 MT in a 20ft, 28 MT in a 40ft

Quality control

Key indices including purity are controlled on the Yellow Grade as well as the White Grade
White Grade is held to the higher purity, melting point and residue-on-ignition limits shown above
TDS and MSDS issued with the order, sample COA on request

Where it is used

Key intermediate in organic synthesis
Pharmaceutical intermediate work using the White Grade
Food additive applications using the White Grade
Industrial synthesis where product colour is not critical, using the Yellow Grade

Who buys it

Fine chemical and intermediate manufacturers
Pharmaceutical intermediate producers
Food additive formulators
Industrial resin and specialty chemical plants

Problems it solves

Paying pharmaceutical-grade prices for an industrial reaction that does not care about colour
Cheap yellow material with an uncontrolled purity that drags down reaction yield
Moisture pick-up in transit ruining an anhydride, addressed by a sealed polyethylene inner bag
Guessing container capacity when planning a shipment

Packing and options

White Grade or Yellow Grade selected against the end application
Standard 25 kg bags with customised packaging available
Inner sealed polyethylene bag with kraft paper or plastic outer bag with liner

How it compares

White Grade versus Yellow Grade is a colour and purity decision, not a quality gamble. If the finished product is visible, ingested or pharmaceutical, take the White Grade at 99.5% min. If the anhydride is consumed in an industrial reaction where colour carries through to nothing, the Yellow Grade at 98.0% min does the same chemistry at a materially lower cost.

Handling and storage

Store in a cool, dry, well-ventilated area and keep containers tightly closed
Keep the inner bag sealed until use because the anhydride is moisture sensitive

FAQ

Succinic Anhydride questions buyers ask

What is the difference between the White and Yellow Grade

Purity and colour. White Grade is white to off-white crystals or flakes at 99.5% min, Yellow Grade is light yellow to yellow flakes at 98.0% min with residue on ignition 0.2% max instead of 0.05% max.

Which grade should I buy

White Grade for pharmaceutical and food additive use, Yellow Grade for industrial applications where colour is not a critical factor. Tell us the end product and the suitable grade is recommended.

How is it packed

A sealed polyethylene inner bag for moisture proofing inside a kraft paper or plastic outer bag with liner, standard net weight 25 kg per bag.

How much fits in a container

20 metric tons in a 20ft container and 28 metric tons in a 40ft container.

Is customised packaging available

Yes, customised packaging is available on request.

What is the water content specification

0.5% max for both grades.

How should it be stored

In a cool, dry, well-ventilated area with the container kept tightly closed.
