Product Overview

Thiamine Mononitrate (CAS 532-43-4), collectively known as Vitamin B1, are white crystalline powders. As an essential water-soluble vitamin and coenzyme, it participates in carbohydrate metabolism and sustains normal nervous system function. Thiamine mononitrate has low hygroscopicity and better stability, while thiamine hydrochloride offers higher water solubility. They are widely used in dietary supplements, fortified foods, beverages and animal nutrition formulations.

Character

Thiamine Hydrochloride: White crystalline powder, freely soluble in water. It features high water solubility, suitable for liquid formulations and pharmaceutical applications. It is hygroscopic and sensitive to high humidity.

Thiamine Mononitrate: White crystalline powder, slightly less soluble in water. Compared with Thiamine Hydrochloride, it has lower hygroscopicity and better stability, ideal for dry powder blends and tablet pressing. It can withstand high-temperature processing conditions.

Main Functions

1.Energy Metabolism Support: Acts as an essential coenzyme, participates in carbohydrate metabolism in the body, helps convert food into usable energy.

2.Nervous System Health: Supports normal nerve function and maintains healthy nervous system.

3.Supports Heart Health: Helps sustain normal cardiac function.

4.Supports Immune Response: Contributes to healthy immune function.

Applications

1.Dietary Supplements

Thiamine Mononitrate is widely used in solid multivitamin tablets and capsules.

Thiamine Hydrochloride is selected for liquid oral supplements and effervescent formulations.

2.Fortified Food & Beverage

Thiamine Hydrochloride is commonly added into functional drinks, liquid nutritional food.

Thiamine Mononitrate is used in cereals, baked goods and solid fortified food.

3.Animal Feed Premixes

Thiamine Mononitrate is the dominant grade for feed premixes due to low hygroscopicity and good stability.

Thiamine Hydrochloride can be used in liquid feed additives.

Packaging & Storage

ECHEMI Editorial Reference

White or almost white, crystalline powder or colourless crystals. Vitamin B1 has an odor slightly reminiscent of thiazole and a bitter taste. When exposed to air, the vitamin rapidly absorbs about 4% of water.
Small white to yellowish crystals or crystalline powder; slight characteristic odour reminescent of thiazole
Thiamine hydrochloride is a hydrochloride obtained by combining thiamine chloride with one molar equivalent of hydrochloric acid. It has a role as an insect repellent. It is a vitamin B1 and a hydrochloride. It contains a thiamine(2+).|Vitamin B refers to several water soluble vitamins often found together in foods, all of which are necessary for normal growth and metabolism, but none of which are synthesized in adequate amounts by humans. The common forms of vitamin B include vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine) and B12 (cyanocobalamin). Except for niacin (when given in high doses), there is no evidence that the other B vitamins, in physiologic or even super-physiologic high doses cause liver injury or jaundice. The major forms of vitamin B and selected other water soluble vitamins (biotin, pantothenic acid, choline) are discussed briefly in this record.|Thiamine Hydrochloride is the hydrochloride salt form of thiamine, a vitamin essential for aerobic metabolism, cell growth, transmission of nerve impulses and acetylcholine synthesis. Upon hydrolysis, thiamine hydrochloride is phosphorylated by thiamine diphosphokinase to form active thiamine pyrophosphate (TPP), also known as cocarboxylase. TPP is a coenzyme for many enzymatic activities involving fatty acid, amino acid and carbohydrate metabolism.

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement
