This insertion impurity contains an additional glutamine at position 19 (duplicated residue) in the Tirzepatide sequence, typically resulting from double coupling during solid-phase peptide synthesis. This reference material supports accurate impurity identification, structural confirmation, and quantitative analysis by HPLC and LC-MS in peptide drug development and manufacturing workflows.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable style=\"border-collapse:collapse;width:90%\" border=\"1\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eAPI Category\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eTirzepatide Impurity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eAppearance\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eOff-white lyophilized powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eCatalog Number\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eBF-TZP-Double-Gln19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003ePackage Size\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e50 mg (custom sizes available upon request)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003ePurity\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e≥95% (HPLC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eSalt Form\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eSodium salt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eCAS Number\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eParent Compound CAS\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e2023788-19-2 (Tirzepatide)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eMolecular Formula\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003eC230H356N50O70\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eMolecular Weight\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e4941.66\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eSolubility\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e20% ACN in water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eStorage Condition\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e-20±5°C, protect from light and moisture\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align:center\"\u003eSynonyms\u003c\/td\u003e\n\u003ctd style=\"text-align:center\"\u003e[Endo-Gln19]Tirzepatide; [Double-Gln19]Tirzepatide; Insertion (double) impurity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e \u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003ePharmaceutical impurity profiling and quality control\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eHPLC and LC-MS\/MS method development and validation\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eDrug substance and drug product release testing\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eStability studies and forced degradation analysis\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eRegulatory submission support (FDA, EMA, ICH guidelines)\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eCustom sizes and specifications are available upon request.
