Analytical Data (Batch Verification Report)
The following data represents the verified results for batch P250722-M21069. Your batch-specific values are available in your Batch Verification Report (BVR) via the verification portal.
| Parameter | Result | Specification | Status |
|---|---|---|---|
| Appearance | White to off-white powder | Conforms | PASS |
| Identity (ESI-MS) | Conforms | Consistent with structure | PASS |
| Purity (HPLC) | 99.34% | ≥98.0% | PASS |
| Water Content (Karl Fischer) | 2.62% | ≤10.0% | PASS |
| Acetate Content (salt) | 2.34% | Report | REPORT |
| Residual TFA † | 18.88% | Report | REPORT |
† Residual trifluoroacetate (TFA) is the counter-ion carried over from synthesis and HPLC purification. This batch is supplied predominantly in its TFA-salt form (not acetate-exchanged). TFA content is a salt-form characteristic and does not affect the reported 99.34% chromatographic purity. Parameters not listed (e.g. residual solvents, endotoxin, microbial limits) were not included on the manufacturer’s Batch Verification Report for this batch.

Frequently Asked Questions
Product Specifications
What is Crystagen?
Crystagen is a synthetic short-chain peptide with the amino acid sequence Glu-Asp-Pro (EDP), a molecular formula of C₁₄H₂₁N₃O₈ and a molecular weight of 359.34 g/mol. This product is supplied strictly as an analytical reference standard for laboratory research.
What analytical data is provided?
Each batch includes a Batch Verification Report (BVR) containing the manufacturer analytical data: HPLC purity (99.34%), ESI-MS identity confirmation, Karl Fischer water content (2.62%), and counter-ion/salt analysis. Access via QR code or online verification portal.
Why does the residual TFA value look high?
Residual trifluoroacetate (TFA) is the counter-ion left over from peptide synthesis and HPLC purification. This batch is supplied predominantly in its TFA-salt form rather than acetate-exchanged, which is why the reported TFA value is elevated. It is a salt-form characteristic and does not affect the 99.34% chromatographic purity of the peptide.
How do I verify my batch?
Three methods: (1) Scan the QR code on the product label, (2) click the verification link in your order confirmation email, or (3) visit celvarislabs.com/verify and enter the batch ID. All provide instant access to your batch-specific Batch Verification Report.
Why does the powder look smaller than other suppliers?
Celvaris peptides are filler-free. Many suppliers add mannitol or other bulking agents to make the powder appear larger in the vial. Our vials contain only pure lyophilized peptide — nothing else.
