QUALITY ASSURANCE

Laboratory Supply & Quality Standards

Every lot synthesized under documented conditions, purified, analyzed by HPLC, and independently verified by a third-party laboratory before its certificate of analysis is published.

VERIFICATION LIFECYCLE

Four steps. Every lot. No exceptions.

Each production lot moves through the same documented lifecycle — and nothing is published until an independent laboratory confirms the results.

01

Synthesis

Solid-phase synthesis under controlled, sterile conditions. Every run is logged to a batch record from the first step.

02

Purification

Preparative chromatography removes synthesis by-products before any lot advances to analytical testing.

03

HPLC Analysis

Analytical HPLC confirms identity and purity against the lot’s acceptance criteria before release for verification.

04

Independent Third-Party Verification

An unaffiliated laboratory re-tests the lot and issues the batch-specific certificate of analysis we publish.

DOCUMENTATION

If it isn't documented, it doesn't ship.

Every lot number resolves to a complete paper trail — from production record to published certificate.

Batch Records

Every production run is captured in a batch record — dates, equipment, in-process checks — retained and reviewable for the life of the lot.

Lot to COA Traceability

Each lot number maps to exactly one certificate of analysis. The lot on your label matches its certificate — never a pooled or representative document.

Published Certificate Library

Batch-specific certificate PDFs from Freedom Diagnostics are published to our open library as lots complete verification.

TESTING STANDARDS

Acceptance criteria, not marketing claims.

Release standards applied to every lot — reported on its batch-specific certificate of analysis.

≥99%

HPLC IDENTITY

Lots must meet or exceed 99% identity by analytical HPLC before release.

MS

MASS SPECTROMETRY

Molecular mass confirmation verifies the expected structure for the lot.

Verified

PURITY VERIFICATION

Lot-level purity is independently verified and reported on the certificate.

LOT-TO-COA MAPPING

FAQ

Storage, handling & documentation

 RUO products are not for human or veterinary use, diagnostics, or drugs. They’re sold solely for laboratory, in-vitro, and R&D applications.

Typically HPLC for purity and LC-MS or MS for identity. Some lots may include additional tests (water content, TFA content, endotoxin) where noted.

 Keep sealed and dry. Short term: 2–8 °C (refrigerated). Long term: −20 °C is recommended.

Our team always ships orders within 1 business day if there are no unexpected delays with our facility or shipping providers.

Freeze-dried powder form that improves stability and shelf life under proper storage.

See each product page for mass (e.g., 5 mg, 10 mg). Vial fill volume is not indicative of mass—refer to the labeled content.
