Everything you need to know about our products and company

Heptamethyltrisiloxane (CAS 1873-88-7), a critical silicone-based compound, is widely used in pharmaceuticals, agrochemicals, and specialty coatings due to its unique chemical stability and surfactant properties. For businesses sourcing this material, understanding pricing dynamics is essential to optimize procurement strategies. Below, we break down the factors influencing its cost and highlight trusted suppliers offering competitive rates.


What Determines Heptamethyltrisiloxane Pricing?​

  1. Purity and Grade
    • Industrial-grade heptamethyltrisiloxane (95–97% purity) typically ranges from ​​15–30 per kilogram​ for bulk orders (25kg+), while pharmaceutical-grade materials (≥99% purity) command higher prices, often exceeding ​​$50/kg​ .
    • Specialized variants, such as 3-ethyl or chloromethyl derivatives, can cost ​​100–300/kg​ due to complex synthesis requirements .
  2. Packaging and Order Volume
    • Smaller batches (10–100g) are priced at ​​5–20 per unit, whereas bulk shipments (200kg drums) reduce costs to ​​1.5–3/kg​ .
    • Custom packaging (e.g., airtight containers for sensitive applications) may incur a 10–15% premium.
  3. Supplier Location and Certifications
    • Domestic suppliers in China, such as ​Hubei Changfu Chemical​ and ​Shanghai Xinsi New Materials, offer competitive pricing with lead times of 5–10 days. International brands like ​TRC​ or ​Alfa Aesar​ charge a 20–30% markup for global logistics and compliance certifications .
  4. Market Demand and Seasonality
    • Q3–Q4 peaks in agrochemical manufacturing often drive prices up by 10–15%. Long-term contracts with suppliers like ​Tiancheng Chemical​ can lock in stable rates .
