Sodium Nitrite Supplier in Malaysia
- Also known as
- NaNO2
- Nitrous Acid Sodium Salt
Sodium nitrite supplier for industrial, technical, food-processing and laboratory buyers in Malaysia. Sodium nitrite (NaNO2), also known as nitrous acid sodium salt, is a white crystalline nitrite salt selected for corrosion inhibition, metal treatment, dye and rubber intermediates, heat-transfer systems and specified food-grade curing uses. It is not sodium nitrate (NaNO3).
Commercial enquiry contexts include industrial grade, technical grade, food grade and high-purity or reagent material, typically as white crystalline powder or granules. Common industrial assays are often around 99%, while food and high-purity grades are matched to the buyer's written specification. Food grade may be discussed in the E250 additive context; curing-salt blends and Prague powder are different products.
Manufacturers use sodium nitrite in closed-loop corrosion inhibition, metal treatment baths, dye and pigment intermediates, rubber chemicals and selected heat-transfer salt systems. Food processors specify food grade material only where the application and documentation require it. Laboratory buyers may need tighter purity or impurity limits.
Send the required grade, assay or specification, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Sodium Nitrite grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Industrial grade sodium nitrite | white crystalline powder or granules | typically about 99% | Closed-loop corrosion inhibition, metal treatment baths, dye and pigment intermediates, rubber chemicals and heat-transfer salt systems where a commercial industrial specification is named. | Confirm the required pack format with the quotation. |
| Technical grade sodium nitrite | white crystalline powder or granules | typically about 99% | General process and manufacturing use where the buyer names technical grade sodium nitrite and states assay, moisture or impurity limits for matching. | Confirm the required pack format with the quotation. |
| Food grade sodium nitrite | white crystalline powder | — | Food-processing applications that specify food grade sodium nitrite, including the E250 additive context for selected cured meat processes. This is pure sodium nitrite grade enquiry, not a curing-salt blend or Prague powder. State the required specification and documents. | Confirm the required pack format with the quotation. |
| High-purity or reagent sodium nitrite | fine white crystalline powder | — | Laboratory, analytical and controlled formulation work that needs tighter purity or impurity limits than general industrial material. Quote against the written specification rather than a generic grade name alone. | Confirm the required pack format with the quotation. |

Common questions about sodium nitrite
Is sodium nitrite the same as sodium nitrate?
No. Sodium nitrite is NaNO2 (CAS 7632-00-0). Sodium nitrate is NaNO3, a different salt with different uses, grades and handling. If your process sheet names nitrite, request sodium nitrite explicitly so the correct material is quoted.
Which sodium nitrite grade should I request?
Industrial and technical grades serve corrosion inhibition, metal treatment, intermediates and general process use. Food grade is for applications that specify food grade sodium nitrite or the E250 context. High-purity or reagent material suits laboratory and tighter specification work. Send the written specification with the enquiry.
What is sodium nitrite used for industrially?
Common industrial uses include closed-loop corrosion inhibition, metal treatment, dye and pigment intermediates, rubber chemicals and heat-transfer salt systems. State the application and any assay or impurity limits so the quotation can be matched.
Is food grade sodium nitrite the same as curing salt or Prague powder?
No. Food grade sodium nitrite is the pure salt, sometimes identified as E250 in food-additive context. Curing salt and Prague powder are blended products that typically combine nitrite with salt or other ingredients. Request pure food grade sodium nitrite only when that is the material named on your specification.
Can packing and product documents be confirmed with the quotation?
Yes. List the preferred pack format and any required product documents in the enquiry. Available packing, documentation and commercial details are confirmed for the quoted grade.
What details are needed for a sodium nitrite price enquiry?
Provide grade, assay or specification, application, quantity and delivery location. Mention food grade or E250 only when required, and confirm the material is sodium nitrite (NaNO2), not sodium nitrate (NaNO3).
