Secure High‑Purity Cetrorelix (CAS 137551‑39‑4) Within 48 Hours — Free Sample, No Commitment
For Purchasing Managers, Technical Directors, and Operations Leaders seeking reliable, cost‑effective GnRH antagonist supplies.
The Real‑World Challenges You Face When Sourcing Cetrorelix
1. Sky‑High Unit Prices – Many suppliers charge a premium for “certified” batches, inflating R&D budgets by up to 45 %.
2. Inconsistent Purity & Potency – Variability between batches forces repeat testing, adding $12,000‑$18,000 per year in QC labor.
3. Lengthy Lead Times – Typical delivery windows of 2‑4 weeks delay clinical trial timelines and jeopardize regulatory submissions.
4. Unclear Regulatory Documentation – Missing GMP, DMF, or FDA certificates cause compliance headaches during audits.
5. Expensive Freight & Customs Fees – Shipping from distant Asian hubs often exceeds $3,000 per container, eroding profit margins.
6. Limited Customization Options – OEM/ODM requests are rejected or quoted at exorbitant rates, preventing product differentiation.
These pain points are not isolated anecdotes; a 2025 survey of 312 US biotech firms reported that 67 % experienced at least one of the above issues within the past 12 months. What does this mean for you? Every delay or extra cost directly shrinks your ROI and prolongs time‑to‑market.

Application Scenarios & Case Studies
Clinical Trial Supply Chain – A US biotech firm needed 2 kg of Cetrorelix for a Phase II IVF study. Our rapid‑scale production delivered the full order in 5 days, cutting their projected timeline by 30 % and saving an estimated $85,000 in storage fees.
Custom Peptide Development – A CRO required a Cetrorelix analog with a modified N‑terminal acetylation. Our in‑house R&D team provided a pilot batch within 10 days**, enabling the client to file an IND submission two weeks ahead of schedule.
GMP Manufacturing for Commercial Launch – A pharmaceutical startup partnered with us for a 500 kg GMP‑grade lot. By leveraging our multi‑site production line, we achieved a 15 % cost reduction versus their previous Asian supplier, while maintaining full audit‑ready documentation.
Frequently Asked Questions (FAQ)
What is the typical purity level of your Cetrorelix (CAS 137551‑39‑4)?
Our standard API is ≥ 99.5 % HPLC purity, verified by three independent analytical methods (HPLC, MS, NMR). Custom higher‑purity grades (≥ 99.9 %) are available on request.
Can you provide GMP‑certified documentation for regulatory submissions?
Yes. Every batch includes a GMP batch record, Certificate of Analysis (CoA), DMF dossier excerpt, and FDA/EMA import permits where applicable.
What are the minimum order quantities (MOQs) and pricing tiers?
MOQs start at 1 g for research use. Bulk pricing for 500 g–5 kg offers up to 30 % discount. For commercial GMP orders, we can accommodate tonnage with customized contracts.
