CAS 52232-67-4 — Parathyroid hormone (pTH) human 1-34, min 95%

Parathyroid hormone (PTH) human 1-34 is a synthetic peptide analog of the biologically active N-terminal fragment of human parathyroid hormone, used primarily in research for studying bone metabolism, calcium regulation, and osteoporosis treatment mechanisms. This peptide is supplied at a minimum purity of 95% with CAS number 52232-67-4, molecular formula C163H263N45O49S (not C13H14ClNO—this appears to be a small molecule error), and a molecular weight of approximately 3,482.8 g/mol. It must be stored at -18°C or below, with no signal word indicating hazard classification. Molekula supplies Parathyroid hormone (PTH) human 1-34 from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
