6-Amino-1,3-Dimethyluracil: A Practical Guide for Industrial Buyers

Specialty chemical buyers need more than a product name and an assay value. They need confidence that the material will arrive with consistent composition, suitable packaging, traceable documentation, and technical support when production questions arise. 6-Amino-1,3-Dimethyluracil  is a specialty intermediate used in chemical synthesis and in selected pharmaceutical and polymer-additive applications. Its CAS number is 6642-31-5, and it is also known as 1,3-dimethyl-6-aminouracil or 6-amino-1,3-dimethylpyrimidine-2,4-dione.

Because this compound can enter different downstream processes, sourcing decisions should be made around the customer’s actual technical requirements. A formulation customer may focus on color and functional performance, while a synthesis customer may place greater emphasis on purity, impurity control, and reaction consistency. A structured qualification process helps both types of buyers select a grade that is appropriate for their production rather than relying on general marketing claims.

Understanding 6-Amino-1,3-Dimethyluracil and CAS 6642-31-5

6-Amino-1,3-Dimethyluracil has the molecular formula C6H9N3O2 and a molecular weight of approximately 155.15 g/mol. Commercial product is commonly described as an off-white to light-yellow powder. These identifiers are useful when comparing quotations, certificates, and shipping documents because similar chemical names can be written in several ways. The CAS number provides a clear reference point during procurement and internal material approval.

Identity, however, is only the first part of qualification. Buyers should confirm the supplier’s specification for assay, moisture or loss on drying, appearance, and any process-relevant impurities. They should also ask which analytical methods are used and whether the production grade is suitable for the intended application. A clear specification prevents confusion between a research reagent, an industrial intermediate, and a formulation-grade material.

Applications in Pharmaceutical Intermediates and Fine Chemical Synthesis

The phrase pharmaceutical intermediates  describes compounds used during multi-step synthesis before the final active ingredient is obtained. 6-Amino-1,3-dimethyluracil offers a substituted pyrimidinedione structure that can be useful as a starting point or building block in established synthetic routes. It is also used more broadly in chemical research and in the manufacture of selected specialty products where its functional groups and reactivity are valuable.

Application suitability should always be confirmed by the customer’s chemists. Reaction conditions, solvents, catalysts, purification methods, and acceptable impurity limits vary from one process to another. A responsible supplier supports this work by providing representative samples and reliable documentation, not by promising universal performance. When the qualification sample and the commercial batch are produced under controlled conditions, scale-up becomes more predictable.

Why Purity and Batch Consistency Matter for 6642-31-5

For many fine chemical processes, inconsistent raw material can cause changes in reaction time, color, filtration, yield, or final-product purity. This is why buyers should evaluate trends across several batches rather than reviewing a single certificate of analysis. A stable supplier should be able to demonstrate that assay and other key parameters remain within a defined range over time.

Packaging and storage are part of consistency as well. Moisture exposure, damaged liners, poor labeling, or unsuitable warehouse conditions can affect a powder before it reaches the production line. Buyers should confirm bag construction, net weight, palletizing, storage recommendations, shelf-life information, and container-loading arrangements. For international shipments, clear labels and batch traceability help receiving teams inspect and release the material efficiently.

How to Compare Chemical Suppliers and Technical Support

A supplier comparison should cover more than unit price. Buyers can create a scorecard for specification fit, sample quality, document response, production capacity, lead time, packaging, export experience, and communication. This makes it easier to identify the offer with the best total value. A slightly lower quotation may not be economical if it creates extra testing, reprocessing, delayed delivery, or inconsistent yields.

Hebei Guangxing Chemical identifies 6-amino-1,3-dimethyluracil as one of its main manufactured products and reports annual capacity for this product. The company also lists quality, environmental, and occupational health management certifications as well as international chemical registrations. These points can support vendor pre-screening, although each customer should verify the documents required by its own quality system and destination market.

Planning Bulk Orders for 6-Amino-1,3-Dimethyluracil

A useful inquiry should state the required product name, CAS 6642-31-5, target specification, estimated quantity, packaging preference, destination port, and requested delivery date. Buyers should also mention whether the material is intended for synthesis, formulation, trial production, or long-term commercial use. This information allows the manufacturer to prepare a more accurate quotation and recommend the right sample or grade.

After sample approval, the purchase agreement should identify the agreed specification and required documents. The first shipment can be treated as a monitored commercial batch, with receiving inspection and production feedback recorded for future orders. It is also useful to agree on how deviations, retesting, and change notifications will be handled before routine purchasing begins. Buyers with recurring demand can share quarterly or annual forecasts so that production and export logistics are planned more efficiently. This disciplined process is especially valuable for companies searching for chemical wholesalers, pharmaceutical intermediate suppliers, or direct factory supply. HBGX Chemical can support customers with samples, certificates, packaging information, and quotations for planned industrial requirements.
