What Is Cetrorelix Acetate?

Cetrorelix Acetate API is a synthetic decapeptide GnRH antagonist peptide API intermediate manufactured for pharmaceutical R&D, pre-clinical formulation development and high-end laboratory research applications. It competitively binds to pituitary GnRH receptors to block gonadotropin secretion, serving as a core active peptide raw material for reproductive endocrine mechanism research and new drug development.

Produced under GMP-aligned production protocols and multi-stage gradient HPLC purification, our Cetrorelix Acetate API delivers accurate molecular structure, stable biological activity and consistent batch quality. As a reliable China Cetrorelix Acetate bulk supplier, HDM BIO provides one-stop API supply, custom synthesis and technical support for global pharmaceutical clients.

What Are the Official Quality Specifications of Cetrorelix Acetate API?

Every production batch of Cetrorelix Acetate API undergoes rigorous analytical testing in HDM BIO's in-house QC laboratory, with a unique batch COA issued for all bulk orders.

Item	Specification	Result
Appearance	White to off-white powder	Consistent
Purity (HPLC)	≥98%	99.01%
MS Identity	Consistent with reference standard	Confirmed
Conclusion	Cosmetic raw material requirement	Passed

Is Cetrorelix Acetate the Same as Cetrotide?

Cetrorelix Acetate is the pure active pharmaceutical peptide ingredient used in the commercial GnRH antagonist medication Cetrotide.

Cetrotide refers to the finished clinical drug formulation, while Cetrorelix Acetate powder is the raw peptide API intermediate supplied for pharmaceutical manufacturing, formulation optimization and laboratory research. HDM BIO provides high-purity Cetrorelix Acetate API raw material rather than finished clinical drugs.

What Is the Mechanism of Action of Cetrorelix Acetate API?

As a high-affinity GnRH antagonist peptide API, Cetrorelix Acetate competitively occupies GnRH receptors on pituitary gonadotrophs, rapidly inhibiting LH and FSH secretion without initial hormonal stimulation. It is widely adopted as a core reference material for HPG axis regulation research, reproductive endocrine mechanism studies and new contraceptive & fertility drug development.

Disclaimer: This peptide API is intended for pharmaceutical R&D and laboratory research only, not for direct clinical administration.
