H-H is a 191-amino-acid peptide hormone produced by the anterior pituitary gland. The recombinant form (somatropin) is chemically identical to the endogenous human version.
- CAS Number: 12629-01-5
- Molecular Formula: C₉₉₀H₁₅₂₉N₂₆₃O₂₉₉S₇
- Molecular Mass (approximate, monoisotopic/exact mass varies slightly by source): ~22,124–22,125 Da (average molecular weight)
- PubChem CID: 16132397 (for somatropin / recombinant human growth hormone)
Notes:
- The CAS 12629-01-5 is the standard registry number for recombinant human somatropin (rhGH).
- Some sources list older or fragment-specific CAS numbers (e.g., 9002-72-6 for pituitary-derived GH or fragments), but 12629-01-5 is the primary one for the full-length synthetic/recombinant form used in research and clinical contexts.
- PubChem CID 16132397 links to the full entry for somatropin (rhGH). Other CID entries exist for specific fragments (e.g., hGH 176-191 is CID 16131230).
This information is for research reference only. H-H and its analogs are strictly for laboratory/investigational use – not for human consumption, therapy, or any non-research application. Always verify with primary sources (PubChem, Sigma-Aldrich, DrugBank) for your specific batch or study needs.
