Diaminopyrimidine Oxide
Diaminopyrimidine Oxide, also known as Aminexil or 2,4-Diaminopyrimidine 3-N-Oxide, is a white to off-white crystalline powder with the chemical formula C4H6N4O and a molecular weight of 126.12 g/mol. It is supplied with a minimum purity of 99.0% and appears as fine granular crystals with low water solubility. This compound is catalogued under CAS 74638-76-9 and is used exclusively as a cosmetic active ingredient, not for pharmaceutical or industrial applications.
The material functions as a hair growth stimulant by inhibiting lysine hydroxylase mRNA expression, which softens perifollicular collagen and prevents fibrosis around hair follicles. It activates IGF and EGF pathways while downregulating TGF-beta 2 and IL-1, promoting anagen phase extension without prolonging telogen. Compared to minoxidil, it operates effectively at concentrations as low as 0.5% and shows no systemic side effects such as hypotension. The powder form is stable under standard storage conditions and is typically incorporated into serums, lotions, and shampoos at recommended doses up to 1.5%.
Buyers include cosmetic manufacturers in Europe, North America, and Southeast Asia who formulate anti-hair loss products. The material is packaged in 1kg, 5kg, or 25kg food-grade polyethylene bags inside sealed drums. Trade terms are typically FOB Shenzhen, with lead times of 7 to 14 days after payment confirmation. A Certificate of Analysis is provided with each shipment, but no third-party certification such as GMP or ISO is claimed by the supplier.

Sourcing Diaminopyrimidine Oxide from Shenzhen Bst Science & Technology Co., Ltd. - China Import Guide
Before placing an order, verify the material’s identity through batch-specific HPLC or FTIR data and confirm that the supplier provides a Certificate of Analysis with each shipment. Ensure the purity meets your formulation needs and that the material is free from heavy metals or residual solvents. Request a sample for stability testing under your packaging and storage conditions before committing to bulk quantities.
Logistics are typically FOB Shenzhen Port, with standard lead times of 7 to 14 days after payment. Confirm the Incoterms, packaging integrity, and container sealing with the supplier. The material is not classified as hazardous under GHS, but confirm the SDS is available in your country’s official language. Payment terms are commonly T/T in advance or L/C at sight, but negotiate based on order volume.
For quality control, perform incoming inspection using HPLC for purity, Karl Fischer for moisture, and visual inspection for discoloration or particulates. Retain a sample from each batch for future reference. Ensure the supplier provides batch traceability and a declaration of compliance for cosmetic use. Document all test results and maintain records for regulatory audits, especially if selling in the EU or US.
