> Carmustine API — Overview
Carmustine (CAS: 154-93-8, also known as carmustine, carmustine API, BCNU, nitrosourea API, and carmustine salt) is a nitrosourea API used in formulation, analytical-development, and research programs where local regulations permit. Suzhou Pharmaceutical Technology Co., Ltd. supplies Carmustine API in controlled small-batch and bulk quantities from Suzhou, China, with export to South America, Australia, New Zealand, Mexico, Canada, and worldwide markets. Export documentation: COA and MSDS standard for all orders.

> Applications
Carmustine is used by pharmaceutical and research organizations developing nitrosourea formulations, reference methods, and impurity-control strategies. API supply is intended for qualified buyers who will confirm dosage form, solid-state and impurity strategy, impurity requirements, pharmacopoeial approach, and finished-dose registration obligations in their own markets.
Nitrosourea formulation research
A 2021 Molecules review summarized nitrosourea and nitrogen-mustard chemistry considerations relevant to analytical development and impurity-control work for alkylating APIs (Molecules, doi:10.3390/molecules26164867). This supports the need for carefully controlled Carmustine API quality in nitrosourea formulation and analytical-development programs.
Analytical and impurity-control development
Buyers typically evaluate assay, related substances, residual solvents, water content, identity, solid-state form, impurity profile, and stability behavior before moving from sample quantities to pilot or commercial batches. We supply API only, not finished dosage forms, compounded preparations, or branded medicines.
> Sourcing & Supply
Suzhou Pharmaceutical Technology Co., Ltd. is an R&D-driven pharmaceutical company with in-house synthesis and analytical capability for Carmustine API. Small batches (up to 10 kg) are produced directly by our technical team in Suzhou. For larger commercial quantities, production is scaled up at qualified manufacturing facilities, with export documentation provided according to the order scope.
- Small-batch orders (≤10 kg): prepared by our technical team in Suzhou. Lead time 10–14 business days from order confirmation.
- Commercial bulk (>10 kg): scaled up at qualified manufacturing facilities. Lead time 14–21 business days depending on batch size and documentation.
We export Carmustine API to buyers across South America — including Brazil, Argentina, Colombia, Chile, Peru, Ecuador, Bolivia, Paraguay, and Uruguay — as well as to Australia, New Zealand, Mexico, and Canada. Inquiries from European, Middle Eastern, and Asian markets are also welcome.
> Quality & Export Documentation
All Carmustine shipments are accompanied by a Certificate of Analysis (COA) confirming identity, appearance, assay, and related substances against batch specification. Purity is tested by HPLC against an authenticated reference standard. MSDS is provided for all orders, and Certificate of Origin (COO) is available for commercial bulk shipments.
| Order size | Documentation included |
| ≤10 kg (small-batch / research) | COA + MSDS |
| >10 kg (commercial bulk) | COA + MSDS + COO |
> Packaging & Logistics
- 100 g, 500 g: double-layered aluminium foil bag, heat-sealed
- 1 kg: aluminium foil bag inside kraft paper box
- 5 kg, 10 kg: aluminium foil bag inside fibre drum
- >10 kg: packaging agreed according to commercial order requirements
Carmustine API is shipped with moisture-protective packaging and batch labels matched to the COA. Shipping options include express courier for samples, air freight for kilogram orders, and sea freight for larger commercial shipments where timing allows.
> Pricing & Supply
Carmustine pricing is provided on request. We do not publish list prices because the final quote depends on order quantity, purity requirement, solid-state and impurity needs, documentation needs, shipping destination, and current raw material costs.
- MOQ: 100 g for qualified buyers
- Sample policy: 10–50 g samples available for analytical confirmation
- Bulk discount tiers apply at 500 g, 1 kg, 5 kg, and 10 kg
- Payment: T/T (bank transfer). 100% in advance for standard orders. Terms for larger repeat orders by arrangement.
