CJC-1295 with DAC Sequence, Molecular Weight & Chemical Identity
3 min read•Published 2025-05-26•Quality Peptide USA Research
CJC-1295 with DAC is a modified 30-amino-acid GHRH analog incorporating a Drug Affinity Complex (DAC). The DAC chemistry forms a covalent bond with circulating albumin, dramatically extending the peptide's research half-life relative to native GHRH or sermorelin. This guide covers sequence & structure for CJC-1295 with DAC — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Primary Sequence
The primary sequence of CJC-1295 with DAC is recorded as: Modified GHRH(1-29) with Lys30 + DAC conjugation. Sequence integrity is verified during release testing using analytical reverse-phase HPLC compared against a reference standard, with mass spectrometry confirming the expected molecular ion.
Molecular Formula and Weight
CJC-1295 with DAC carries the molecular formula C152H252N44O42 and a calculated monoisotopic weight of approximately ≈ 3367.9 g/mol. These values are essential for accurate molar-concentration calculations during reconstitution and for normalizing dose curves across studies.
Identifiers and Synonyms
CAS Registry: 863288-34-0. CJC-1295 with DAC is also referenced in the literature under its full chemical name and developmental designations. When searching publications, querying both the common and chemical names typically surfaces the broadest body of work.
Structural Notes for Researchers
CJC-1295 with DAC is supplied as a lyophilized solid with a white to off-white appearance. Researchers should reconstitute in sterile bacteriostatic water unless their assay calls for a specific buffer (e.g., 0.1% acetic acid for hydrophobic peptides). Quality Peptide USA publishes the full chemical-identity card on every product page so that incoming-QC checks can be performed against a known reference.
