Product Overview

Triptorelin is a potent GnRH agonist that has been extensively studied in academic and preclinical research settings for its interactions with the hypothalamic-pituitary-gonadal (HPG) axis. As a synthetic analogue with enhanced receptor binding affinity compared to endogenous GnRH, it serves as a valuable tool compound for researchers investigating neuroendocrine signaling, receptor pharmacology, and reproductive biology. The Peptide Store is proud to offer this compound for sale online with transparent quality documentation and competitive pricing.

Peptide Structure & Amino Acid Sequence

Triptorelin is a decapeptide with the amino acid sequence: pGlu-His-Trp-Ser-Tyr-D-Trp-Leu-Arg-Pro-Gly-NH₂. The substitution of D-tryptophan at position 6 distinguishes it from native GnRH and confers significantly increased metabolic stability and receptor binding potency. Its molecular formula is C₆₄H₈₂N₁₈O₁₃, with a molecular weight of approximately 1,311.47 g/mol. The CAS number for triptorelin is 57773-63-4.

These physical properties make Triptorelin a well-characterized and reliable reference compound for GnRH receptor studies and related neuroendocrine research programs.

Purity & Analytical Verification (HPLC & MS)

Every batch of Triptorelin (GnRH) supplied by The Peptide Store undergoes rigorous analytical testing to confirm identity and purity. High-performance liquid chromatography (HPLC) is employed to verify that purity meets or exceeds the ≥98% threshold, while mass spectrometry (MS) confirms the correct molecular mass and structural integrity of the peptide. Certificates of Analysis (CoA) reflecting these results are available upon request, ensuring full traceability and analytical transparency for research teams and institutional procurement officers.

Quality Control & Lyophilization Integrity

Triptorelin is manufactured using solid-phase peptide synthesis (SPPS) under controlled conditions and subsequently lyophilized to remove residual moisture, extending shelf life and preserving structural integrity during transport and storage. Each vial is sealed under inert conditions to prevent oxidative degradation. The lyophilization process is validated to ensure consistent cake formation and rapid reconstitutability, which are critical parameters for reproducible laboratory workflows.

Safety, Handling & Laboratory Precautions

This compound is supplied strictly for laboratory research purposes. Personnel handling Triptorelin should follow standard laboratory safety protocols, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coat, and eye protection. Avoid inhalation of powder during weighing or handling. This material has not been evaluated for safety in human or animal subjects and must be treated as a potentially hazardous research chemical. Dispose of all waste in accordance with applicable local and institutional regulations.

Reconstitution, Packaging & Storage

Triptorelin is supplied as a lyophilized powder in a sealed, sterile-capped glass vial suitable for laboratory handling. For research reconstitution purposes, researchers should consult peer-reviewed literature and institutional SOPs relevant to their specific assay requirements. Store lyophilized vials at −20°C in a dry, dark environment away from repeated freeze-thaw cycles. Once reconstituted for in vitro use, solutions should be aliquoted and stored appropriately to maintain peptide stability. The Peptide Store recommends reviewing published protocols for guidance on buffer selection and concentration ranges appropriate to your research model.
