Sermorelin is the N-terminal 1–29 fragment of human growth-hormone-releasing hormone (GHRH), a single unbranched chain of twenty-nine L-amino acids (single-letter YADAIFTNSYRKVLGQLSARKLLQDIMSR) finished with a C-terminal primary amide in place of the free acid — the feature encoded in the (1–29)NH2 designation. Position 15 is glycine and position 27 the lone methionine, which contributes the single sulfur atom, and the sequence computes exactly to the molecular formula C149H246N44O42S (average mass 3357.93 g/mol; monoisotopic 3355.8187 Da). The identity is reconciled against PubChem CID 16132413: molecular formula, isomeric SMILES and the stereo-defined InChIKey WGWPRVFKDLAUQJ-MITYVQBRSA-N all match a peptide assembled independently from the sequence (thirty-one stereocentres, none unassigned). The CAS number 86168-78-7 denotes the free peptide; the historical acetate salt carries a separate registry number.

Reference context

Sermorelin is a synthetic 29-residue peptide amide corresponding to residues 1–29 of human growth-hormone-releasing hormone (GHRH), also written GRF(1–29)NH2 — the N-terminal fragment of the 44-residue parent sequence, capped with a C-terminal primary amide. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C149H246N44O42S and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Sermorelin is characterized

Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The residue sequence and the modifications noted above define the structure.

The CAS number 86168-78-7 denotes the free peptide; the historical acetate salt carries a separate registry number.
What is the molecular formula of Sermorelin?
Sermorelin has the molecular formula C149H246N44O42S, giving an average molecular weight of 3357.93 g/mol and a computed monoisotopic mass of 3355.8187 Da.
What are the key chemical identifiers for Sermorelin?
The CAS Registry Number for Sermorelin is 86168-78-7. Its PubChem CID is 16132413, its FDA UNII is 89243S03TE, and its InChIKey is WGWPRVFKDLAUQJ-MITYVQBRSA-N.
Is Sermorelin a peptide?
Yes. Sermorelin is a peptide — a chain of amino-acid residues joined by peptide bonds, 29 residues in length. Its identity is defined by that sequence and its molecular mass.
How is Sermorelin stored and reconstituted?
As a research material, Sermorelin is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.
Does Lineará sell Sermorelin?
No. Sermorelin is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.
Is Sermorelin approved for human use?
No. Sermorelin is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
