L-Alpha-Glycerylphosphorylcholine (Alpha GPC) sourcing overview
L-Alpha-Glycerylphosphorylcholine (Alpha GPC) is presented as a specification-first B2B catalog entry associated with CAS 28319-77-9. Buyers can use the fields below to prepare a comparable RFQ without treating a generic product name as proof of grade, quality or suitability.
Procurement context: The catalog name identifies a specific commercial material, but it does not define a universal grade, purity, composition, physical form or approved use. Match the complete offered specification to the buyer requirement.

Identity details to preserve
- Exact catalog name: Use “L-Alpha-Glycerylphosphorylcholine (Alpha GPC)” as the initial requested name and resolve any supplier synonym to the same documented identity.
- CAS screening reference: The catalog associates 28319-77-9 with this listing. Verify the number on the offered specification, SDS and COA before approval.
- Written alias or qualifier: Keep the parenthetical text “Alpha GPC” in the enquiry until current supplier documentation confirms its exact role.
- Written form qualifier: The written qualifier “L-” is identity-relevant and should not be removed when comparing documents or quotations.
How to specify L-Alpha-Glycerylphosphorylcholine (Alpha GPC)
Use numerical acceptance limits and named test methods wherever they matter. The following fields help turn a name-only enquiry into a comparable specification brief.
- Exact identity: Confirm the preferred chemical or ingredient name, CAS or other identifier, and every written salt, derivative, source or stereochemical qualifier.
- Grade and assay: State the required grade, assay or purity basis, acceptance range and named analytical method.
- Impurity profile: Define the related substances, water, residual solvents, elemental impurities, microbiological limits or other controls relevant to the project.
- Physical criteria: Specify the required supply form and any particle-size, viscosity, density, solubility, colour or handling criteria that affect processing.
- Commercial scope: Provide sample and forecast quantity, pack size, storage, destination, timing, Incoterm and document requirements.
Documents and sample review
For a proposed L-Alpha-Glycerylphosphorylcholine (Alpha GPC) option, request the current product specification and a representative or recent certificate of analysis. Ask which supporting files are applicable and available, such as an SDS, TDS, origin statement, allergen or GMO statement, residual-solvent data, contaminant testing and destination-market compliance documents.
Evaluate documentation and a representative sample against the buyer’s own analytical, formulation, processing, stability, safety and regulatory criteria before bulk approval. Document and sample availability is confirmed for each enquiry.
Comparing L-Alpha-Glycerylphosphorylcholine (Alpha GPC) quotations
Why should quotations be compared against a full specification?
The same short product name can cover different grades, assay methods, physical forms and impurity limits. A line-by-line specification comparison makes the quoted identity and quality basis clear.
Is CAS 28319-77-9 enough to approve the material?
No. A CAS number helps screen identity, but it does not define commercial grade, concentration, physical form, impurity limits, test methods, packaging or regulatory support. Compare those fields on the offered specification and COA.
Request a quotation for L-Alpha-Glycerylphosphorylcholine (Alpha GPC)
Send the exact product name “L-Alpha-Glycerylphosphorylcholine (Alpha GPC)”, CAS 28319-77-9, required grade and acceptance limits, intended professional use, sample and forecast quantity, pack size, destination country, target date, Incoterm if known and required document list. Derreva can then review the enquiry against current supply information and coordinate the appropriate next step.
