COA Overview

QA Policy

Each batch is released only if it meets SynerGen’s internal HPLC purity threshold. If any finished batch does not meet specification, it is rejected and re‑manufactured prior to release.

Typical release specification: ≥ 98.7% (HPLC).

Identity

Methods may include MALDI‑TOF or ESI‑MS, amino acid composition, and sequence confirmation as applicable for each peptide or compound.

Purity (HPLC)

Reversed‑phase HPLC at 214 nm is used as a primary purity assay. Passing criteria are typically set at ≥ 98.7% area, with chromatograms kept on file.

Water & Residue

Karl Fischer moisture and residue on ignition (for inorganic content) may be performed according to internal procedures and research‑grade expectations.

pH & Appearance

pH may be assessed on a 1% w/v solution within a defined window. Visual inspection is performed for color and appearance, typically white to off‑white lyophilized powder.

Bioburden & Endotoxin

Bioburden screening may include TAMC/TYMC testing aligned with compendial guidance for research materials. Endotoxin monitoring can be performed using LAL (gel‑clot or kinetic, as applicable) for process hygiene benchmarking.

Status Notes

• In Stock items typically have HPLC results recorded and released as “≥ 98.7%” before being offered.
• In Production items are noted as “Pending production/QC release” until testing is complete.
