Sodium Butyrate

CAS No.: 156-54-7
Chemical formula: C4H7NaO2
Molecular weight: 110.09 g/mol
Grade: Feed grade

Sodium Butyrate Powder, feed grade, CAS 156-54-7, is the sodium salt of butyric acid supplied as a white fine powder at 98% min assay, 98.0-101.0% on a dry basis. It is the dry-dosing option for intestinal health programmes: it improves gut development, enhances immunity and reduces the need for antibiotics in livestock and aquaculture, and unlike the liquid glycerides it blends straight into a dry premix. Shelf life is 24 months, packed 25 kg per bag.

Why buyers specify this grade

Assay 98% min, specified 98.0-101.0% on a dry basis, so the butyrate contribution is known
White fine powder that blends into a dry premix without a liquid dosing line
Drying loss 2.0% max, keeping the powder free flowing
Heavy metals as Pb 0.001% max and arsenic 0.0002% max
24-month shelf life, 25 kg per bag with custom packaging available

Quality control

Released on assay, clarity of solution, pH, drying loss, heavy metals and arsenic
TDS, MSDS and sample COA available for Sodium Butyrate in the document centre

Where it is used

Intestinal health and gut development support in livestock feed
Growth performance programmes in poultry and swine
Aquaculture nutrition
Antibiotic reduction strategies in feed formulation

Who buys it

Feed mills without liquid dosing equipment
Premix manufacturers
Poultry, swine and aquaculture nutritionists
Producers reducing in-feed antibiotic use

Problems it solves

No liquid addition system on the feed line, which rules out the glyceride liquids
Poor gut development in young stock holding back growth performance
Reliance on in-feed antibiotics under regulatory or customer pressure
Caking and poor flow in a premix from a wet or hygroscopic additive

Packing and options

25 kg per bag standard with custom packaging available
Dose rate advised against species and production stage

How it compares

Sodium butyrate is the most economical way to get butyrate into feed and the only one of the three that dry-blends without special equipment, but much of it is released in the upper tract. Monobutyrin and tributyrin are the glyceride liquids to specify when release further down the gut is the objective.

Handling and storage

Store in a cool, dry, well-ventilated place and avoid direct sunlight
Blend into the dry premix; no liquid addition equipment is needed
Use within the 24-month shelf life

FAQ

Sodium Butyrate questions buyers ask

What is the assay

98% min, specified as 98.0 to 101.0% on a dry basis.

Is this coated or uncoated

This item is supplied as sodium butyrate powder, a white fine powder at the specification shown. Tell us your release requirement at enquiry.

What is the shelf life and packing

24 months, packed 25 kg per bag with custom packaging available.

How does it compare with tributyrin and monobutyrin

Sodium butyrate is a dry powder that blends into a premix without liquid dosing equipment, but releases butyrate mainly in the upper tract. The glycerides release further down the gut.

What is the pH of solution

9.0 plus or minus 1.0 measured on a 1.0 g per 50 ml aqueous solution.

Are documents available before ordering

Yes, TDS, MSDS and a sample COA are available for Sodium Butyrate in the document centre.

How should it be stored

Cool, dry and well ventilated, out of direct sunlight.
