Product Overview
Urea — also sold as carbamide or carbonyl diamide — is a solid organic nitrogen compound, CAS 57-13-6, offered here in technical grade pellet form. It is one of the most widely used nitrogen sources in industry: fertilizer blenders, feed formulators, resin producers and synthesis operations all run on it. Alliance Chemical offers it to order in 5 lb and 50 lb pack sizes from our Taylor, Texas distribution operation.
This is a listing for working buyers. Urea is not classified as hazardous under GHS based on available data (per the product's GHS classification), which makes it one of the simpler materials on a purchase order — but storage discipline still matters, because moisture exposure degrades handling quality and can raise a slight ammonia odor. The sections below cover what our warehouse team actually deals with when packing and shipping this product.
Why This Concentration
Technical grade urea is the workhorse designation for industrial use. Buyers blending fertilizer, formulating non-protein nitrogen feed supplements, or charging a urea-formaldehyde resin reactor typically specify technical grade because the process consumes the material in bulk and the economics matter more than a technical-tier designation. The grade label describes the procurement tier, not a specific monograph or certification — if your process has a defined specification, review the TDS and the lot-specific COA against it before you commit a production run.
Pick this product when you need dependable solid urea in pellet form at industrial scale. If your application is a regulated technical or technical use with a compendial requirement, confirm the documentation supports that requirement first; do not assume it from the grade name.
Chemical Profile
Urea appears as odorless white crystals or pellets; this listing supplies it as pellets. It is denser than water at a density of about 1.34 and will sink rather than float, which is worth knowing if you dissolve it in open tanks. It is soluble in water — dissolution is straightforward and is how most process users charge it. Vapor pressure is very low, at 0.000012 mmHg, so the solid itself contributes essentially nothing to airborne vapor under normal conditions. Fresh material is odorless, but it may gradually develop a slight ammonia odor, especially in the presence of moisture — a practical freshness cue our warehouse team takes seriously and the reason dry storage is the single most important handling rule for this product. The molecule is CH4N2O with a molecular weight of 60.056; the compound is noncombustible. CAS number 57-13-6 is the identifier to match on your SDS, COA and purchase order.
Industrial Applications
Urea's value is simple: it is a concentrated, solid, water-soluble organic nitrogen source that dissolves cleanly into whatever process needs nitrogen.
-
Fertilizer production.Urea is a foundational high-nitrogen input for fertilizer blending and formulation. Blenders dissolve or dry-blend the pellets into finished products that deliver nitrogen for plant growth.
-
Animal feed supplementation.Feed formulators incorporate urea as a non-protein nitrogen source in ruminant feed programs, where rumen microbes convert it into usable protein equivalents. Formulation and inclusion rates are the nutritionist's call — work from your own feed specification.
-
Chemical synthesis.Urea serves as a precursor and reactant in the synthesis of downstream chemicals and technical intermediates. Synthesis buyers should match the COA against their input specification for each lot.
-
Urea-formaldehyde resins.Resin producers react urea with formaldehyde to make adhesives and coating resins — one of the largest non-agricultural uses of this molecule.
-
Technical and microbiology work.Urea is used in biochemical assays and as a nitrogen source in microbial culture media. Labs with tight input requirements should review the TDS before substituting a technical grade material into a validated method.
Handling & Storage
Urea carries no GHS signal word and is not classified as hazardous under GHS based on available data (per the product's GHS classification). That said, our handling guidance — reviewed by Andre Taki, DOT Hazmat Specialist — is to treat every industrial chemical with baseline discipline: wear gloves and safety goggles when scooping or charging and work with adequate ventilation to keep dust down.
Storage is where this product is won or lost. Keep it cool, dry and sealed. Moisture is the enemy: damp urea cakes, handles poorly and may develop that slight ammonia odor. Store away from incompatible materials, out of direct sunlight and high heat and keep containers closed between uses. HDPE and glass containers are appropriate for decanted material. Follow the SDS for the full storage and incompatibility picture.
Hazmat & Shipping
Urea is not regulated as a hazardous material for transport — it carries no UN number, no hazard class, no packing group and no hazmat proper shipping name (per 49 CFR 172.101). For a receiving dock, that means this product moves as ordinary freight from a transport-classification standpoint. We state the classification only; carrier services, routing and any receiver obligations are governed by your carrier and your site's own procedures. Our team packs solid chemicals for ground transit the same way regardless of classification: sealed, labeled and matched to the paperwork.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French and Japanese — useful for multi-site EHS programs and international documentation files. A technical data sheet is available for specification review before purchase and a lot-specific Certificate of Analysis is available for buyers who need to verify each lot's purity data against their own acceptance criteria. If your quality system requires documents up front, request them with your quote and we will supply them before the material ships.
Why Buy from Alliance Chemical
This listing runs from a 5 lb bench pack to 50 lb production packs, with SDS coverage in four languages and lot-specific COAs available — a documentation stack sized for buyers who answer to a quality system, not just a shopping cart. Alliance Chemical has operated as an industrial chemical distributor since 1998 and has served more than 55,000 customers from our Taylor, Texas warehouse. Shipping and handling guidance on this page is reviewed by Andre Taki, DOT Hazmat Specialist. If you are scaling from samples to standing orders, talk to us about recurring supply.

C&EN and CAS reported on 5 October 2026 that deep eutectic solvents are still mostly a research story. The most-studied pairs are choline chloride with urea, ethylene glycol or glycerol; a 1:2 choline chloride-urea mixture freezes at 12 C from parts that melt at 302 and 133 C. Water decides whether a recipe reproduces: the structure breaks at about 51 wt% water, and glyceline made from a 25 percent glycerol solution is 63 percent water. Two Solids Make a Liquid.
